I would like to create a certain material in order to use it in Unity. It is foam and it looks like this:

enter image description here

To create such a material, I have constructed a pyramid:

enter image description here

How could I now bake a normal map from the pyramid?

The pyramid would be the "high poly model", and then I would need a low poly model, right?

If yes, what should I choose for a low poly model? A cube?

Thank you very much for the help!

I don't think you need to make a Normal map to do this.

  1. Add a plane. Extrude it along the z axis a little..
  2. Select the top face and subdivide it as you need. Extrude them to match the height of the foam pyramids.
  3. Select the pivot point to 'Individual Origins' and scale them to 0
  4. Remove doubles from the W key menu.

  • $\begingroup$ Thanks, but I don't understand what your approach is. I really need the normal map, I can't do this with geometry unfortunately. $\endgroup$ – tmighty Jul 20 at 1:44

  • $\begingroup$ Sorry for the late reply. I tried baking a normal map from it but it doesn't seem to work when applied to a plane. Maybe I am missing something. $\endgroup$ – AshKB Jul 21 at 13:36
