I have a working shader that has colored alpha dots to give the illusion of a glow.
In the DIFFUSE slot is a normal solid texture.
The OPACITY slot is blank.
The SPECULAR slot has the alpha texture which is a DXT5.
Is it possible to have the alpha texture fade in and out so basically you only see whats in the DIFFUSE slot, then both the DIFFUSE and SPECULAR, then back to just the DIFFUSE slot/solid texture, and keep repeating in this way?
