I all, I'm new at this place (not very used to blender). I would like to make a key chain with a extruded logo. I found a tutorial on how to use displacement image to mold my keyring the result look like a vacuum formed shape but it almost like what I have in mind. The problem is that i'm using a "grid mesh" so the keychain is actually only a thin layer, how can i make it a fill object? Thank You K.
