Okay, I am creating a ground texture in photoshop. I created an alpha map for it, by creating two layers.http://img168.imageshack.us/img168/8391/groundtexturescreenshotqu4.jpg
Could I just simply save this as a .tiff image and it would work? can it be 1024x1024? Is it possible to have more than one ground texture?
By the way, this is a desert map I am creating. It has a old pavement road going thorough the center, only interrupted by a railroad track with a derailed train on it. I have a lot of great ideas for it.
