Hi Rob Pento, You are in the Punch Professional section, but you wrote the Material Editor (do you mean the Material modifier?) you probably have Platinum8, so, just in case, these are the options Punch AS 4000: you can import new textures using Power Tools--> Material workshop Platinum 8: you can try to modify the current brick textures (colors and sizes) with the Materials Modifier (Power Tools--> Materials Modifier) Other Punch versions: you can replace the current textures with your own textures. Notice that this procedure may (or may not) cause interferences with some power tools. You can read RB's instructions to elaborate this http://www.punchhelpers.com/rb_resources.html Hope this helps Patricia
