bending materials
I have a colored tube that I want to add some text and have the text follow the curve of the tube. (kind of like writing on a garden hose) I tried making the tube a cylinder, adding a colored material, and added a second material that had “color” set to bitmap image of the text and “alpha channel” also set to the bitmap image. With material positioning, everything worked as I wanted, but when I added a bend deformer to the cylinder, the material no longer followed the curve. I tried every type of material mapping without success.
I then tried making the tube from a sweep nurbs composed of a circle and akima spline. Adding the first colored material was not an issue, but adding the second material with the bitmapped image and alpha channel still does not seem to follow the curve.
How would you do this? Thanks.

Make sure you use UVW as your projection type on the Sweep NURBS object (which should be the default method). Other than that use the Stick Texture tag, just like Nolan said.

Thank you for your responses. How does one add a stick texture tag? I tried UV mapping but for some reason I can’t get the text to show. I’ve tried rotating the model and changing the tiling settings without success.

Thank you very much!

Thanks again for all the help. I tried things both ways and discovered the initial problem was that there were two copies of the image file with alpha and the material didn’t seem to want to accept reassigning the original image file. I just recreated a new material and everything worked well.
The bending with tag set to stick texture worked somewhat but had some artifacts with circular rings still coming in at a bit of an angle. The sweep nurb worked better with UV mapping.
I tried several ways to rotate the colour texture file in C4D with UV mapping but was unsuccessful. I eventually just rotated it on PS and it worked well. I can easily rotate texture with cubic, spherical, etc mapping but can’t seem to figure out how to do this with UV mapping. Is there a way?

You can do this with the Layer Shader. Add a layer with your image file and then add an “Effect>Transform” layer. Inside the transform layer you can rotate the tex to any angle you desire.
