I am using Photoshop CS5 and created a cylinder 3d layer (3D -> New Shape from Layer) from a seamless clouds texture. I wanted the image to be warped like a tube, and succeeded, but the tube is convex; I want to be looking at the INTERIOR surface of the tube. This is a common procedure in 3d modeling programs called "flip normals" or "reverse normals". How can I do this in Photoshop?
- This has nothing to do with generating a "normal map" for a 3d model, this is using newer 3d object features, which can map 2d layers to 3d objects, generated within Photoshop.
- I can settle for a displacement filter that "wraps" the edges of the layer, but I don't see anything like that
