I'm working on an art test right and I have a section of torn up wood planks. The texture has no white in it yet I'm getting this white border around the alpha, anyone see this before?
its not white. Its partly transparent.
The very edge there is from the antialiasing of the alpha map and how your renderer is handling it.
If you run a levels on your alpha map and ensure that you are only getting black and white(move both the arrows to the center) and that will go away.
I bet this is happening because you have the Diffuse bitmap's Alpha Source set to "Image Alpha". This causes the Diffuse bitmap to mix its colors with the Diffuse color.
Either change the Diffuse bitmap's Alpha Source to "None (Opaque)" or set the Diffuse color to black.
