Lights in 3d intersection, shadow problem

Hi,
When setting 2 shapes (plane) in 3D so that they have and intersetion (say 30degrees offsett), and one smaller then the other, when putting a light into the scene, to make the small one cast a shadow on the big on, the shadow looks good, but not at the intersection part. Why do I see shadow in the intersection, this should be just a clean intersection...
Helge

I had some shadow behavior problems a few projects ago. While they were not the same as yours, I discovered that the "Shadow Softness" parameter on the light was making things behave improperly.
Try setting the "Shadow Softness" parameter to "0". That made things behave properly for me.
Apple has contacted me about this problem and I have provided them with my project files in order to help their engineers debug the shadow issues. Hopefully there will be a patch soon.
Good-luck

Who can shed some light on my ongoing connection problem.
After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
I tried all things of resets and forgets. No result.
I have been fondling with my Airport Extreme 5 , but that did not help much.
This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
Ideas anyone ?

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

LIGHT DOESN'T CAST SHADOWS.

hi i have a few layers, a camera, and an ambient light. i turn cast shadows on in every layer but it doesn't do anything. i did the same thing a long time ago on another video and it worked, but that was the one and only time it did, what am i doing wrong?

> i turn cast shadows on in every layer but it doesn't do anything.
the light must also be set to cast shadows but Ko is correct, ambient lights do not have that option.
the online help system will explain it all to you.
Double-click a light layer in the Timeline panel or select the layer and choose Layer > Light Settings.Casts Shadows Specifies whether the light source causes a layer to cast a shadow. The Accepts Shadows material option must be On for a layer to receive a shadow; this is the default. The Casts Shadows material option must be On for a layer to cast shadows; this is not the default.Light Type Parallel emits directional, unconstrained light from an infinitely distant source. Spot emits light from a source that is constrained by a cone, like the spotlight used in stage productions. Point emits unconstrained omnidirectional light, like the rays from a bare light bulb. Ambient creates light that has no source but rather contributes to the overall brightness of a scene and casts no shadows.

Photo border / shadow problem

On iweb (and until recently on my website - www.megevechalet.co.uk) the pictures had a nice light shadow. iweb still shows the light shadow, but on the website all the photos now have a thick black border. Does anyone know why this might have changed and what i can do to resolve it? I'm absolutely certain I've done nothing on iweb to change it and haven't actually been on iweb for about a month (until today when i checked to see that on iweb the shadow is still showing).
Any help would be gratefully received!
Thanks

Are you using Firefox to view the site and see the black boxes? That's a problem with FF and some other browsers on photos that have had frames, drop shadows, borders or reflections added to it.
There's an easy workaround that removes those black boxes, reduces the number of files needed to render the page and speeds up the loading of the page. Follow the workaround described in this tutorial: #7 - Converting Photos w/Frames, Drop Shadows and/or Reflections into a Single Image File.
It works very well.

AI to Fireworks drop shadow problem

Hi,
I'm importing .AI files into Fireworks in order to export them as .pngs because the raster quality is better than out of .ai,
One of my files has a white box with a 100% black drop shadow on a grey background. In AI it looks fine, but when I open the file in Fireworks the shadow appears white, a bit like a glow.
The shadow is set to 'Multiply' and has worked in other files.
Any ideas why it's doing this? It's only on this file.
See below:
Thanks

This is a bit off-topic, but it relates to how Illustrator and Fireworks sometimes handle rasterization of vector objects differently, and I thought you might find it interesting. (This was done using Illustrator CS2 and FW8; I can't say whether CS5 behaves the same way or not.)
The basic question is this: Where does a 1-pixel stroke belong on a vector object that's aligned to a bitmap grid?
In Illustrator, with Snap to Pixel enabled (in Pixel Preview mode), the vector itself is aligned to the bitmap grid, and a 1-pixel stroke is balanced across both sides of the vector—appearing in effect as a lighter, 2-pixel, anti-aliased stroke. The result looks very imprecise. You can fix this by setting the Keyboard Increment (in Preferences) to 0.5 pixels, turning Snap to Pixel off, and nudging the object a half pixel in each direction using your keyboard arrow keys: Now the stroke, not the vector, is aligned to the bitmap grid.
Theoretically, you should be able to adjust stroke position to handle this issue; however, I found that setting the Stroke to "Inside" produced an unexpected bit of anti-aliasing on one side of my rectangle. (This type of problem may have been fixed in a newer version of Illustrator.*)
In Fireworks, vector objects tend to snap to the pixel grid automatically, as do strokes. But how can FW do this? After all, the default stroke position is center-aligned, just as it is in Illustrator. Well, it turns out that the application is willing to bend the rules a bit: A 25-pixel square with a 1-pixel stroke applied to it still only occupies 25 pixels on the grid, because Fireworks moves the stroke to the inside of the object. It cheats. Once you bump up the stroke weight to 2 pixels, the stroke alignment reverts to center. At 3 pixels, the stroke remains center-aligned but becomes anti-aliased, too.
So anyway... I hadn't really sat down with Illustrator's Pixel Preview mode before. Despite the issues above, I think it's kind of neat in that it's like a window into the world of Fireworks and pixel grids. (In Fireworks, by contrast, you don't have the option of seeing vectors rendered smoothly at any zoom level, as in Illustrator's standard view mode.) I can't recall whether Preferences can be saved in a Workspace, but View settings can at least be saved as part of a template file, and you could probably set up a de facto workspace for working with pixels in Illustrator in a relatively short amount of time. This could help you avoid surprises when using "Save for Web" (as described in the article to which you linked).
*Later, I was able to fix the "stroke inside" rendering problem in Illustrator by setting the stroke to .99px instead of 1px.

Print quality for light gray gradients and shadows

Hello all,
I am putting together a single page flyer which will have light gradients and shadows on the objects.
Think Apple-ish light grays and shadows...
I would like to get an opinion here from someone in the know as I am much more of digital guy than print.
1) What is the lightest gray I can work with that would print well?
When setting up the CMYK color should I simply set it at say 10% 10% 10% 10% or is there some better mixture for light gray gradients. i.e. slightly blue for example, or rich black mixture.
2) When creating the gradients in illustrator, should I go from the gray to transparent or is it better to set up a gray to white gradient?
Finally,
When creating my supporting images with the shadows and gradients, would it be best just to create them in Photoshop and place them in my illustrator document and leave Illustrator for the text alone?
Thanks in advance, I really appreciate your help

Let's assume you are working in Illustrator. Here's my advice:
Hello all,

"I would like to get an opinion here from someone in the know as I am much more of digital guy than print.

- It should not be necessary to use 10% across the board. It comes down to how you want the shadows and gradients to appear. You ask what is the "lightest" Gray. That depends on the press and paper. Let's also assume you are planning for high end offset on a high end glossy "White" stock ( paper ). A 10% Black is fairly reasonable, but you could plan for 5%K ( again, depends on press and paper ). A nice warm Gray could be achieved with 7.5%C, 7.5%M, 7.5%Y, 0%K; a nice cool Gray could be achieved via 2.5%C, 0%M, 0%Y, 7.5%K. I would cross check a Pantone Process Color Guide for a reasonable choice. Do not rely on the monitor.
2) When creating the gradients in illustrator, should I go from the gray to transparent or is it better to set up a gray to white gradient?
- It should not be necessary to set your gradient to transparent. A typical scenario would be K > 0W; only specific requirements demand transparency.
Finally,
When creating my supporting images with the shadows and gradients, would it be best just to create them in Photoshop and place them in my illustrator document and leave Illustrator for the text alone?
- That depends on the file, the background, and a few other considerations. The key to shadows and gradients in Illustrator is they be applied as part of the final step in the file prep process. If you create the shadows, for instance, in Photoshop, the end file size may end up larger than you anticipated. And, the shadow would be resolution dependent ( less flexibility ).
Thanks in advance, I really appreciate your help"
Before you get started with your file, contact the print vendor to find out what type of press and what type of paper they plan to use on your job ( of you haven't already ). Don't forget to set your document resolution in Illustrator ( assumed ) and the Raster Effects resolution. Another important thing to remember is nail down the actual Gray ( i.e., lookup in Pantone Process Color Guide printed on the paper type you plan to use on press ).

Using Bridge to Camera Raw to Open Image button also drop shadow problems

I remember when I was working with RAW in PSE 8. I would be in Bridge looking at a pic and double click on it. PSE 8 would open in Camera RAW and I could play with the pic a bit, make some adjustments, then click on OPEN IMAGE. When I did that it would open in PSE and it would be in jpg format. With this PSE 9 and the updated Camera RAW 6.3, when I punch OPEN IMAGE I still have a picture labeled .CR2 which I think still means RAW. When I double click in Bridge the .CR2 pic shows as 8 bit depth. I can do a little more work on it and use SAVE AS. When I do that, the sample file name that shows is still in .CR2 format and I must change that to .jpg and then below change from PHOTOSHOP to JPEG to save my file as a jpg file. Is there something that I have to change in preferences to get it to open the image in jpg format when I hit the OPEN IMAGE button? Or, is this an "improvement" with RAW 6.3? Also, I seem to be having trouble adding a drop shadow (or any other effects) on jpeg pics. At least it doesn't show up on the screen after I apply it. I just recently updated to Camera RAW 6.3 and updated my Operating system on my iMac computer to OS 10.6.6. I emailed this request to my good friend with an identical setup on his iMac and he is having the same response when performing the above operations. Any ideas what the problem might be?

Okay, previously you seem to have been using the bridge version of camera raw to edit your raw photos. That has many more options than the PSE version of the raw converter. (If you still have PSE 8, you can see the difference by using File>Open in the editor to open a raw photo for the PSE version of ACR, which works the same way in PSE 9.) In PSE's raw converter, you use the Open button, then save your photo in an image format in the editor. The Save button in ACR in PSE is only the DNG converter.
Layer styles should work exactly the same way as in PSE 8. However, in any version of PSE a drop shadow, like a real shadow, needs someplace to fall, so unless there is empty space on the layer, it won't appear. Try creating text or drawing and simplifying a shape and adding a drop shadow. Does it appear then?
Also remember that Jpegs won't let you save either layers or transparency when you resave the file.

Box shadow problem in IE 8-9

I want to place CSS drop shadows on different objects on a web page. It works perfectly in Safari, FF, Chrome and Opera both in Widows and OS X, but fails in IE 8 & 9. Any help would be much apreaciated. VL Branko
Here is the CSS:
/* this is for putting drop shadows on images that are placed in the text area which is generally white or very light colored */
.dropshadowtext {
-moz-box-shadow: 5px 5px 8px #999; /* Firefox */
-webkit-box-shadow: 5px 5px 8px #999; /* Safari/Chrome */
box-shadow: 5px 5px 8px #999; /* Opera and other CSS3 supporting browsers */
-ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color=#999999)";/* IE 8 */
: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color=#999);/* IE 5.5 - 7 */
/* this is for putting drop shadows on images that are placed in areas other than the text area */
.dropshadowbackground {
-moz-box-shadow: 6px 6px 5px #35454c; /* Firefox */
-webkit-box-shadow: 6px 6px 5px #35454c; /* Safari/Chrome */
box-shadow: 6px 6px 5px #35454c; /* Opera and other CSS3 supporting browsers */
-ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color=#35454c)";/* IE 8 */
: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color=#35454c);/* IE 5.5 - 7 */
/* this is for putting a drop shadow under the area where there text is written color of shadow will depend on the background*/
.dropshadowunderwritingarea {
-moz-box-shadow: 6px 6px 5px #35454c; /* Firefox */
-webkit-box-shadow: 6px 6px 5px #35454c; /* Safari/Chrome */
box-shadow: 6px 6px 5px #35454c; /* Opera and other CSS3 supporting browsers */
-ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color=#35454c)";/* IE 8 */
: progid:DXImageTransform.Microsoft.Shadow(Strength=4, Direction=135, Color=#35454c);/* IE 5.5 - 7 */

I was away for a few days hence late reply. I removed the MS filters from the CSS but it still didn't work in IE9 when I check in browser lab.
I see that you have a demo of how to do it for various versions of IE at
http://alt-web.com/DEMOS/CSS-Shadows.shtml
It worked when I checked in browser labs. Are you no longer recomending this? How would you implement it in CSS?
As for the validation errors they seem to be artifacts left over when converting from Adobe Golive to Dreamweaver. More deadwood to clean out.

Color flicker? Florescent lights? Viewer to Canvas problem?

Hello everyone,
I shot on a Sony HZ5u,
in Smooth Slow Record,
HDV1080i, 60i
inside a semi truck bay under fluorescent lighting (I think).
In both the Viewer and Canvas there is a frame to frame shift in White Balance hue
from cyan to magenta.
The issue does not occur outside the bay, so I'm guessing it's due to lighting.
Now my problem is that the visibility of this is more noticeable in the Canvas
where there is an extreme flicker. It hurts my eyes. It is very rapid.
*Is there a reason why it gets worse in the canvas? How can I fix this?
It is not my monitors, I moved both windows over to each monitor and it's consistent.
And for anyone who knows, why does this camera, and other cameras, react so drastically to normal fluorescent lighting?
I have had earlier issues where the color did not flicker but rolled, like a tv static roll, slowly and constantly.
Thank you for ANY help!
Landon S.

No it's the other way around.
If you shot at 60i/30fps with today's cameras you may not have a problem, even with the old magnetic ballasts with a florescent bulb you're really not at odds with the AC cycle at 30fps. It's when you shot slo-mo and change the frame rate to something that's not divisible into 60Hz that you get in trouble.
Of course all that changes if the the AC current isn't stable.
There are little tricks like not using auto white balance, and using proper shutter speeds. I'm not much of a shooter, I've just come across the problem before and understand the cause. I produced a film shoot in a newsroom once where we had to re-light the whole room and bag the florescent lights.
We ran tests, it's smart to run tests. If you shoot in that place again I would bring in your own lights.

Shadow problems

Sorry if this question has already been asked...I'm having some frustrations with shadows in Pages. I have placed a colored shadow behind a photo and then altered the shadow to appear more like a glow around the photo. However, when I go to preview, print or try to export as PDF, the shadow is reverted back to a normal shadow and not the glow effect that appears in Pages. So far, I've been unable to print this project the way it appears in Pages.
Is there something I'm missing here, or is this a bug in the program?
Thanks.

Hello AH1462,
if the PDF-X advice from Ric doesn't solve your problem, try the more detailed tut at: http://discussions.apple.com/message.jspa?messageID=1247733#1247733. If that doesn't work, try to use Acrobat Destiller or Pro (if you have). Print the Pages file into a PS and import it to Acrobat, than save it as a PDF.
If that doesn't work as well, you can be full of hope for a new version of Pages in January like a lot of us are.

Drop Shadows problem in Acrobat Reader & Professional

Hi all,
We have a problem with Acrobat, when we open an pdf which has drop shadow over a background seems to be white patch around the dropshadow.
Attempt done:
First Attempt: Opened the PDF in acrobat professional 7, when we switch on overprint option this seems to be good but when I print I got the white patch around the dropshadow.
Second Attempt: Opened the PDF in Acrobat Reader 9.0, it has white patch and print has white patch.
Third Attempt: Opened the PDF in Acrobat Professional 8, when we switch on overprint option looks fine and print fine.
Client want the pdf should be compatible in Acrobat Reader.
Note: This PDF was generated with 3b2 Software we cannot switch over the software to Indesign.
Any suggestion related to this issue.
Kaviya

The overprint settings would need to be set in the source file and preserved when generating the pdf. Based on the information from the uploaded file, you might try Arbortext Advanced Print Publisher support.

Drop shadow problem

Hi,
We face the below mentioned problem. Would be great if someone could help us.
Due to problems with uploading the attachment here, please send a email to the following email-id ([email protected]) and I shall send the attachment in response.
Problem Description: Clicking dropshadow in air component should bring focus to other application behind the air application.
Steps to Reproduce:
1. Open any applications in full screen. ( ex : MSWord, Notepad )
2. Run the DropShadow sample.
3. Click the shadow portion in the panel component.
Actual Result: Clicking the shadow area in the panel component is setting focus to the same DropShadow application.
Expected Result: If some other application are opened in fullscreen ,then clicking the shadow area in the panel component should change the focus to the applications which is behind DropShadow application.
Thanks in advance.

After looking at your code your application is behaving as it should. Essentially your flash element is defining a drop shadow. It is part of your application therefore when the user clicks on it, it's like clicking on the rest of the application.
Some programming languages get around this by using regions and relying on the operating system to generate the drop shadow (when available.) For instance in a C# application you would define a region, clip everything outside of it (so that it is transparent) and then use the windows API to shadow your application. When using the API the OS then uses it's rules to define whether you clicked on the application or not. This also leads to all sorts of weirdness when you have anti aliased window shapes (curves and the like) and do not want them to look terrible.
So AIR applications handle this by allowing you to have completely transparent windows if the underlying window manager supports it. The drawback then is that you are not using the OS to define your shadows and so your shadows are part of the application window and clickable. On the plus side AIR allows for a great bit of flexibility that is not so easily attained in other ways. (I once lost about 2 weeks of my life on a C# app just getting rounded edges to not look extremely horrible.)
For an illustration consider if you created a custom popup menu that was 50% transparent. For all intents and purposes to AIR that is identical to the drop shadow you are creating here however in that instance you would want it clickable etc.
Hope that helps!

Drop shadow problem with Illustrator CS5

I've used drop shadow several times with no problems in both photoshop and Illustrator... currently I'm dropping a white shadow onto a black background and although the shadow drops correctly around the object I've noticed that there is some sort of extra white blur that is happening several inches away from my images reguardless of what shape they are. Let me know if a file would help and I can email an example of the problem. Thanks

Wade, This does look like the exact problem I'm having. I do not want to make a clipping mask because I have around 20 pages with numerous images on each page of varying sizes... I tried- Effect/Document Raster Effect Settings, Under options I played with a couple different settings but none seem to have fixed the problem... There is a check box for;
Anti-alias
Create Clipping Mask
-Add _____ in. Around Object
Preserve spot colors
I'm not familier with these settings and didn't know what you were recommending I change exactly?
Thanks again for the help

Churn/Intersect MDX problem

Hi All,
I would like to see your approach of calculating churn based on the intersect of dimension members with MDX. Do you believe it is advisable to do it directly in the cube based on the dimension with more then 10 million records?
Here's the problem.
I'd like to calculate the following:
Clients this month - clients the same month previous year.
Simple right? Well, it gets trickier. The comparison needs go down to the grain which is the client, meaning, i cannot compare raw numbers (which are distinct count measures in the cube btw) but the actual client ID's. I tried playing around with intersect
but i really need a simple example first before I start adding complex logic to the calculation (like fixed parameters for one batch and not the other, conditional logic over another dimension's attribute etc..).
Any good ideas and approaches to solving this problem?
Thanks!

Hi L,
It's a pity my demo site isn't still online. Here's a blog about churn. http://richardlees.blogspot.com.au/2008/12/blog-post.html
The mdx might look something like
with
member Measures.LastMonth as count(filter(Customers.Customer.Customer,(Measures.NetSales,[Time].FiscalCalendar.prevmember)<>0))
member Measures.RetainedThisMonth as count(filter(nonempty(Customers.Customer.Customer,Measures.NetSales),(Measures.NetSales,[Time].FiscalCalendar.prevmember)<>0))
member measures.R as
iif(Measures.LastMonth=0,null,
Measures.RetainedThisMonth/Measures.LastMonth)
, format_string="#,#.00%"
select {LastMonth,RetainedThisMonth, measures.R } on 0
,nonempty([Time].FiscalCalendar.[Month],Measures.NetSales) on 1
from sales
Hope that helps,
Richard

Drop Shadow Problem in CS3

I'm running PS CS3 in Win7 and have noticed an odd problem. I have a psd with a layer in which I've knocked-out or erased the background. I've got a forground subject and the rest is transparent. I've got another layer beneath it. I had a drop shadwo and when I increase the Spread all is ok. Then I increase the Size and I see a whole bunch of drop shadows that have nothing to do with the forground subject.
There's something there in the layer to cause the shadows. I've tried several different layers with different colors to reveal whatever is there. I can't see anything. However if I use the wand, I can select "something". If I erase or mask in the location of the drop shadow, it disappears. Something is there, why can't it be seen?

Something is there, why can't it be seen?
Because technically, even 0.00001 opacity is not 100% transparent and you are human - your eye can't discriminate such small differences in color and your computer can't display it to begin with, either. Beyond that you have pretty much answered your own question - they are stray pixels with very low opacities and you have to clean them up properly.
