Nice try MadDog!.. using the same technic you now may try to model the windows with the same terrain.. I mean just one terrain for the wall and all the windows details.. The technic I use for the texture is quiet simple, I start from a real brick wall pic.. I set my working window (photoshop) to 1024 X 1024 or 2048 X 2048 for more details.. and I choose the same terrain resolution in bryce 1024 or 2048.. I create the grey level map from the wall pic, adding the details I want for the windows and the doors.. then in the Bryce texture editor I apply my texture (image) and I try some different diff and ambiant setting.. I dont use any bump map as it's given by the grey level map on the terrain.. here is an exemple.. and believe me it works well!.. Hope this will help you to improve your Artwork. Cheers
