Quote - I was referring to the use of Photoshop to create the shape template for a lattice,which technically isn't a texture,but the source of the shape itself.While this can be done in the terrain editor,it is very difficult to create a complicated shape.Just want to make sure this doesn't break the terms and disqualifies my entry.

Well I would say it was still a texture, even if it is used to create a lattice. So yes, perfectly acceptable.
