I'm wanting to create a rotating 3D logo/object using a layer from photoshop. After changing to Ray-traced 3D and going to the geometry option the bevel options are not available and it remains in 2.5D. I'm not sure if I missed a step or if what I'm trying to do is not possible,
The extrusions only work on Text and Shape layers, not pixel data. This works completely different than in Photoshop. You need to bring in your contours as vector paths via copy&paste or as an Illustrator file that you convert to a shape layer.
ditch the obsolete ray-traced renderer and go for the real thing!
Or ditch Cinema 4D and get a "real" 3D program? Just saying... *lol*
