Alpha channels and team glow

Ok, pretty much what I want is to make an engine glow with team glow, but I want it to always be orange, regardless of the team colour. Plus, I'm having troubles with the alpha channels. Do you have to make it a special material for alpha channels? Because all I did was make it wc3 material, then put the bitmap on it. Do I need to do anything else?

You need to put the filtermode for the texture in the model to additive. Also to get that teamcolor just point the texture to the teamcolor texture which can be found in ReplaceableTextures\TeamGlow\ or something.

Ahh good it worked. Thank you.
