One additional note concerning trap textures. Notice that when you add a trap texture the parameter "Texture amount" becomes visible. This is part of the trap texture parameter block, and is something you can vary. "Use Transformed Coordinates" also becomes visible and can be checked. Not all textures will show a change when this is checked. It depends upon how the formula writer coded their trapshape/texture.
