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?

Extra notes:

  • 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

Photoshop is not the best package for creating 3D objects, it's not a complete 3D editor. As far as I know, you can't. You can either:

  1. Create the tube using an extruded ring, so you have normals facing inside.
    1. Select a shape layer (a vector ring in this case)
    2. Choose 3D > New 3D Extrusion From Selected Path, Layer, or Current Selection.
  2. Get a 3D software and create your 3D shape there, where you'll have better control of the model. For a simple tube there are many free 3D softwares that would work.
  3. If you have an Adobe CC subscription: Go to After Effects, from there select File > New > Maxon CINEMA 4D File or Layer > New > Maxon CINEMA 4D File. You can then render your cylinder and re-import to Photoshop if necessary.
  • Thanks. I solved this by rendering a rotating seamless cylinder in Unity, back in November – hatinacat2000 Aug 19 at 9:22
  • Yeah sorry for the late reply, I don't think I saw the question earlier. – Luciano Aug 19 at 9:27
