I have a simple texture, of a bush (for a billboard plane) There are very annoying white artifacts around the edge of the plane.
I am using GLSL shading in the BGE.
UV/Image Editor 3D View
There is no white edge on the actual texture, however, one appears on the plane.
Texture Settings are Below, Material Settings are below and to the right
Get the ones that start with Bush1_ and Plants_
