Problem with the 3d part of photoshop CS5

Question

Dear everybody,
im trying to follow a PS tutorial on the web, which is quite good i think (http://psd.tutsplus.com/tutorials/3d/create-a-shiny-earth-with-photoshop-3d-layers/comment -page-1/#comments) , but i run upon a problem which is next:
At part 11, he tells me to: 'The weather seems to be too cloudy, because we can see the clouds that are on the other side through the transparent areas. Making the material one sided will fix that problem. Uncheck Two Sided.
As you can see, he can uncheck that, because he is in CS4 i think. But in CS5 you can not uncheck that, although, i can't.
Can someone please tell me/explain to me where i can uncheck that? Because i really can't find it.
Thanks in advance.

Hi Jordi,
The option to light both sides of a material was removed in CS5. Having said that there are a few other ways to achieve the effect presented in the tutorial. The quickest way is to go to 3D> Render Settings... and check 'Remove Backfaces' in the Face Style options. What is happeing is the inside and outside surfaces are getting rendered, and since the cloud 3D layer is effectively 'in front' of the earth 3D layer you are seeing more than wanted. By removing the backface, you no longer render the inside surface.
Another method is too merge the 3D layers so the clouds become a shell that covers the earth. Doing it this way you can also light and shade the earth with the clouds and not need to use the Layer Styles drop shadow method.
Hopefully that makes sense.
