"Blend" Tool Problems

Hi, I am using CS and the “blend” tool to create a train track but I cannot seem to get the spacing to look right. I tried adding a 3rd railroad tie in the middle but that didn’t work either. Any ideas how I can get more spacing in the foreground and less in the distance?

Comp,
You may also do this in a simple (or maybe not so simple) 2D way.
Your first and topmost/smallest sleeper/crosstie shaped as a trapezium has a certain height H (basic width of sleeper as seen at the viewing angle) and two horizontal segment lengths, the top length W (basic width/length of sleeper) and the larger bottom length WB; you may wish to adjust the length of the bottom segment to get the desired growth in width; you can see the misfit between the angle and the growth in your image(s) yielding a ragged appearance.
You have to decide the relation between the height and distance between the sleepers, and have the angle at the ends fit the desired growth in width.
If you settle for an approximate solution (which is probably only insignificantly inaccurate) where each distance between sleepers has a certain ratio R to the height (width on the ground) of the previous one, you may:
1) If needed, adjust the length of the bottom segment (see below);
2) Effect>Distort & Transform>Transform with Horizontal Scale = Vertical Scale = 100+(1+R)*(WB-W)*100/W%, Vertical Move = -(1+R)*H (negative value), and the desired number of Copies.
If you dislike the growth of the width, you may repeat 1) and 2), starting with an adjustment of the length of the bottom segment, then recalculating.
If you dislike the ratio of distance to height, you may just repeat 2).
To illustrate, if you start with a first sleeper having H = 2, W = 20, and WB = 21, and a distance ratio R = 1 (same distance as width), you will get the following values in 2):
Horizontal = Vertical Scale = 100+(1+1)*(21-20)*100/20 = 100+2*1*100/20 = 110%
Vertical Move = -(1+1)*2 = -4.
Number of Copies as desired (19 for 20 sleepers in total or similar).
Obviously, the greater the relative difference between WB and W (the further from a rectangle), the lower the viewing angle and the faster growth in the size of the sleepers.
And obviously, the greater the ratio R, the less dense appearance.
Here are images based upon H = 2 and:
A) W = 20/WB = 21/R = 1 (Horizontal = Vertical Scale = 110, Vertical Move = -4)
B) W = 40/WB = 24/R = 1(Horizontal = Vertical Scale = 105, Vertical Move = -4), and
C) W = 20/WB = 21/R = 2 (Horizontal = Vertical Scale = 115, Vertical Move = -6):
You (probably) do not want to know how to do it for full (insignificantly improved) accuracy.

Blend tool problems with distributing objects.

Hi Everyone,
First time here so I hope this is the appropriate forum locale for this specific question - of which I have not found a solution online or in these forums.
I have dealt with this problem for quite some time and am sick of manually correcting blends so I am seeking help.
Here is the situation:
I draw a simple oval, copy it and move it somewhat diagonally across the page. I then resize the oval slightly (thinner) but retain the same amount of anchor points.
I then rotate the oval about 2 degrees.
Next I apply a blend - hoping it will blend the two shapes evenly (like it did in pre CS versions) but the blended ovals get closer to each other on one side than the other - so it seems to be a weighting problem... so I checked out each of the blend options and even tried the various methods of making a blend (via panel, or pull down menu, hot keys, etc.) Nothing works to get the shapes evenly spaced. Distribution and alignment panel offers no help either and in some cases makes the objects distribute more unevenly.
Summary: If I make two IDENTICAL shapes/ovals, the blend works fine... but once I modify one of the ovals, before or after the blend is made, even in the slightest bit, the distribution spacing gets skewed/uneven.
I don't think it is a bug since I've had this problem since early CS days. Is anyone else having this problem?
I hope it is an easy fix. I am using a PC version of Illustrator, if that matters in this case.
Thank you ahead of time for your consideration and help.

I've tried all those options (distribute spacing, distribute objects, specified distance, specified steps, etc) without success... it wound up just being the 'ol visual issue described above and the manner in which I set up my illustration.
So after I create a blend, I try the various options to get the objects to align / distribute correctly (to fix the visual issue), but after, say, applying "distribute spacing", the ovals arc slightly so that they are not aligned in a straight manner from end to end.
I then try other alignment options and nothing seemed to correct the alignment from one oval to the next... thus I had to correct it manually.
Anyways, I found that if I set up my illustration so as to do my oval blends on a horizontal or vertical axis (without transforming one side, but keeping them all the same - in a grid-like pattern) and then Free Transform the group of ovals afterwards to indicate perspective and the like -- that seems to be a reasonable solution.
I also learned a new trick in this process / forum post.
I won't be able to reply for a while... All is well now and I gotta get to work, so it's literally back to the drawing board for me.
Thanks again! =)

Blend tool doesn't create smooth blends - how do I fix this?

Hey guys and gals,
I can't seem to figure this one out. When I use the blend tool for a smooth blend, the blends comes out jagged and horrible, as if it is doing a step blend rather than a smooth blend. I have used the tool before by either using the shortcut (Alt+Ctrl+B) or using it via the Object>Blend pathway and it worked out fine, but now Illustrator doesn't want to create a smooth blend.
What I'm trying to say is; is there an option that is causing this to happen that I may have accidently turned on, or has my copy of Illustrator gone into stupidity mode and I need to reinstall it?
I've attached pictures of what I mean with the settings I'm using and outputs. I hope your collective minds can smack this one in the face. I'm sure I'm doing something ridiculously simple to cause this.
I'm using CS5 Illustrator and my relevant PC hardware is listed below.
- Intel i5-2500 3.30Ghz
- nVidia GeForce GTX 560
Thanks in advance.

In this case, the sawtooth patterns corrspond to the corners of the large number of different intermediate shapes sticking out.
So basically the shapes straight edges and corners are the cause of my problem, the smooth blending I was experiencing earlier which appeared smoother was actually because I was using a more rounded shape?

Blend tool isn't sticking to its shape

Hello, I have been having issues with using the blend tool on my object. If you look at the picture, I had one outer shape that was what I wanted shaded and a thinner shape that runs inside the other. It blends perfectly fine everywhere except at the bottom. I don't know how to explain it or what went wrong but I can't figure out how to make the blend fit inside the shape.

Well, you half fixed my problem. I deleted two points where you said and the big gap between the legs disappeared but it seemed to have broken every other part of the body. Believe me, I've been messing with adding and subtracting points now but it keeps altering between what you see in this picture and back to the big gap between the legs.
Edit: After messing around with it for awhile I got it to fit with the shape. Thanks everyone for the help. My points weren't lining up within the two shapes, I guess.

Laptop mode tools problem with kernel 3.0

today I just updated the system and my laptop runs dramatically hotter after that. I read the archwiki, it does talk about the laptop mode tools problem with kernel 3.0 but when I opened the file /usr/sbin/laptop_mode, the lines which the wiki mentions are not there. Does anyone here have the same problem and can you offer the solution?
Here is my /usr/sbin/laptop_mode

# This is a 2 phase locking approach. LMT_REQ_LOCK is the outer lock and LMT_INVOC_LOCK is the inner lock
# We take this approach to ensure the scenario that, "At any point when an event occurs (AC/BATT), the
# kernel can generate multiple events spanning over a couple of events. The first event is honored and
# lmt executes. If the last event triggered at the 9th second, there is a fair chance that a good amount
# of state change would have occured in the OS, to honor that state, we keep an outer lock (LMT_REQ_LOCK)
# handy, so that those changes can also be applied and not forgotten.
# Workflow:
# Event-1 is generated and lmt executes (lmt runtime could span 5-10 seconds)
# At seventh second, 4 events generate. But Event-1 is still running.
# We don't want to discard all the remaining 4 events, but at least honor 1 so that we can act to the changes
# that occured in the last 7 seconds.

I had the problem but edited the line in /usr/sbin/laptop_mode and it worked. But thoes lines are not there anymore. I guess they changed it at the recent update of laptop-mode-tools.
Regarding your heat problem; is there any other thing you use to cut down power usage (from AUR maybe)? I use acpi_call from AUR had to edit lines there aswell, but it should be updated by now.

Blend tool to objects with no fill (transparency)

Is it possible to create a blend using the blend tool with one of the objects to be blended being transparent (having no fill or outline)? If not, could someone please suggest an alternate solution? I know I can do something somewhat similar with gradients but I really like the level of control blend provides.
Thanks much in advance
Joe Stavitsky

You mean, opacity of the object I'm blending "from"? But the, wouldn't the object I blend "to" still be opaque?
Thanks again
Joe
EDIT
Never mind, you're quite right - thanks so much!

Weighted Blend Tool

I would like to see weighting added to the blend tool. So the user can define the spacing to be smaller on one side and further apart on the other, similar to Ease In/Out in Flash.

Yes, that's true and works great if your blend is completely straight. But if your blend follows along a more winding path it doesn't allow you to keep your original curve. In other words, in order to spread out copies at one end, you need to use the Convert Anchor Point Tool on the path and drag out a handle. This changes your path. What if the blend needs to be a certain shape? The bigger the effect you want, the more you'll end up distorting the path you want to keep.

Using blend tool to create even transitions between shapes

When I use the blend tool I notice that the blends from large to small and the distance between the objects are based upon the center of the two shapes. I blended the squares on the outside and the gaps between the blended squares aren't even. Is there a way to blend the shapes and have even gaps between the new objects?

the goal would be to create a blended square effect (or any object) to fit a stroke variation of this style
to this
and the objects would be blended again to this (filled with the squared blended pattern)
if I'm not making sense, which I'm probably not, I can show you what the pattern would look like with the uneven blended squares. It looks way off and far too spaced out between the objects by the time the stroke fades out to its final weight

Color blender tool and other questions

Hey. I've got Photoshop CS4, which I've been using pretty successfully for digital and pixel art, but there's still a lot to the program that's unknown to me, and trying to google up an answer isn't getting me anywhere. I've got a few questions.
Is there some sort of color blender tool in CS4? By color blender, I mean something that will easily let me pick two separate colors and generate a range of colors that are between them. The tool at http://meyerweb.com/eric/tools/color-blend/ is an example of a program that does what I'm hoping Photoshop can do.
Is there a way to simultaneously view my canvas both zoomed in and at it actual size as I draw? This is mainly for pixel art, where the art close-up can look really different from the actual product. A little actual-sized canvas in the corner of my screen that updated as I made changes to the art in zoom in would save me the time I spend fiddling with magnifying glasses.
Is there was way to keep the smudge tool at full opacity? When using it, smudging edges of color onto a blank space makes them start to get transparent. As of now I just get rid of it by multiplying the layer a few times and then merging, but is there a way to disable that?
If there are no definite ways to do these things, any suggestions or guides you know of would be useful too. Thanks!

Hello!
Select the gradient tool, it is an alternate tool to the paint bucket one (Hit Shift+G until you see it replace the Paint Bucket tool)
Double-click on the gradient you see in the option bar, you will then get the gradient editor http://help.adobe.com/en_US/photoshop/cs/using/WSfd1234e1c4b69f30ea53e41001031ab64-77dfa.h tml
Double-click on the first color stop to get an eyedropper, sample your first color, do the same with the end one, and the second color.
Once your gradient is created, you'll be able to lay down a gradient, and pick the middle color with the eyedropper tool.

Wierd Poly Lasso Tool problem

Hi, I just started using PS on Mac, and having a polygonal lasso tool problem, when I make any selected area with the poly lasso and complete the shape, say for instance a series of sun rays, it ends up with a bunch of boxes in the shape, that I didn't put there, I'll attach a screen shot, any idea what is going on?

Hi, yeah, i tried that, have there been any bugs that relate to the polygonal lasso tool?
heres a post with the same problem, but no fix- this seems really silly

Brush Tool problems

I am having an ongoing problem with the Brush Tool in my PSE9.
I have the question written out in Word Pad but I can't seem to copy & paste it into this box. The 1st thing I need to know is how to copy & paste my simple text question here.

Barbara B.:
It has been several days since I heard anything from you on my ongoing Brush Tool problem. From your digging what have you found? In the past 10 days I have continued spotting B&W negative scans & trying to collect additional information on the propensity of the brush tool to create a line running across the image. Basically what I have found reinforces the 7 points/factors I outlined in posting #14 on 7/7/12. I'll go over & expand on those again here.
1) When the line runs it always goes from where I am currently spotting to some point I previously clicked & put a spot. This is not necessarily the most recent spot. It can travel to a spot I did 30 sec. ago (& have done several others in the interim). It does need to be on the visable portion of the screen.
2) As stated. The width of the line is the same as the width of the specific selected brush size. Usually between nos. 4 & 9. The tone of the line is the same as the tone selection (so far I have only experienced this with B&W).
3) The more I spot the slower the computer's reaction time becomes. After spotting for an hour, or two, I will see several seconds between the time I click on a spot & the time the spot actually appears on the negative. I have tried turning off PSE & rebooting it. This seems to speed things back up for a while.
4) When the situation in #3 occurs I obviously can't click rapidly.
5) I still don't understand why this happens at all. I move the curser outside of the image frame towards the Vert. & Horz. slider as I get ready to move to a new part of the image. I place the curser on the slider control a left click (as though to move the slider). Instead of moving the slider it shoots one of these lines out onto the image from under the slider control & out onto the image field to some point where there was a previous spotting click. These lines will often run half way across the image field. I have saved some of these examples & could attach them to an email for you to see.
6) Once one of these lines start appearing, or running, they seem to increase with frequency. Almost as though the software is developing a memory. As I say in #3, if I re boot PSE the memory either is erased, or at least reduced.
7) The only time the original statement is not totally true is when a line runs from under the slider (which is outside the viewing area) out into the visable image field.
Here are some additional factors I have noticed:
8) I normally begin spotting by setting the view drop down to "actual pixels". I notice that If I further magnify the image by then clicking once on the "zoom in" option I have a reduced frequency if these wild lines appearing. This may be due to the fact that when the image is larger I am working (stippling) at a slower rate.
9) If I have a hair or scratch on the neg. (normally using a drawn line to obliterate) & I use a stippling/clicking pattern rather than a drawn line the frequency or chance of a free running line is reduced - not eliminated, but reduced

Blend Tool Help

After using the blend tool I want to turn the lines into paths and then outline the strokes. How do I do this? Attached are two images. One showing the image and one showing the image when selected. Only the two beginging lines have a path that is editable, how do I break this up so all the lines are editable paths.
I hope that made sense.
thanks.

Don't even bother with attachments. They get "queued" which means, as far as I can tell, nothing, except everyone must wait hours or days until the image is available for viewing. Meanwhile, since we don't see what you're trying to show us, we don't respond and your post drops lower and lower until nobody sees it or answers your question.
If you want to post an image use the Camera icon to Insert Image. If you want to post a file for downloading, like a PDF, zip, or AI file, then post it online elsewhere and instert a link.

Blend tool vs. Gradient Tool

I am doing up some artwork that requires a blend in the background from blue to white. I originally used the gradient tool but when I got a test print done, I didn't like the "banding" that was visible...it wasn't as smooth as I'd like. Is this a printing issue or would I be better off using the blend tool for a smother gradient? If so, would I set it up with a certain number of steps, or just pick "smooth". I'd appreciate any advice! Thanks.

I'd also ask on what device the test print was made and on what device the job would ultimately be output.
Banding is often caused by proofing devices that require large color space conversions. Lacking sufficient bit depth, the calculations for such conversions can result in dynamic-range-related artifacts, such as banding. Such artifacts are not necessarily representative of actual press conditions.
Adding "dither" as Scott suggests is always a good idea. However, I'd also check with your output service provider as to reasonable expectations and proofing alternatives.

Blend tool bug?

Hi!
I am trying to make a "3D-ish" button by using the blend tool. It works fine on the first two layers-they blend together just fine. But when I try to put a third (gradient layer that is set to screen transparancy before blending) layer on top it won't work as it is supposed to. See below. What am I doing wrong?
When I drag the blend tool cursor over the button no "line" appears. Anyone knows of this "bug" or what I am doing wrong? Please help!

Looks like that object is rotated. Maybe just dragged the rounded rectangle tool in another direction when drawing that object. Use the blend tool to create the blend and click on corresponding anchors with it.
