I am trying to map some moving text onto the ouside of a half cylinder. I have made a circle in illustrator, used this as my 3D object. I have placed the layer map texture on the beveled part of the object and add transparency.
This all working great except….I do not want to see the texture part showing up on the flat side of the cylinder. How do I prevent this from happening?
Above the set-up window, click the material set-up button. That will bring up a cross section of your object with six bays into which you can place different materials. Simply drop whatever material you want into one of the empty bins and drag the number to the part of the cross section where you want it to be applied. You can split edge cross sections as well. If you need help with that, please let us know.
Thanks for the file. It helps me to understand what you’re doing.
A couple of comments: You’ve used a 100 percent transparent material on the front and rear faces of the object. You can avoid having to deal with any materials at all by unclicking the front and rear faces under the objects tab. They won’t be seen.
Second, I think you’re saying you don’t want the text to appear on its entire path around the edge of the object. You can do this by adding masks to the left and/or right edges of the text layer. Use the masks to make the text insvisible for part of its motion across the layer. Another way to do it would be to create visibililty keyframes.. to turn the visibilty of the text on and off when you want it.
