I have made this pure white image in photoshop (the skills on me...).

I want to bring it to csgo / hammer but it's a bit glitched. There it looks like:
This are the options I used in VTFEdit: (I just noticed it's on animated texture, but I doubt that is the problem, but I will try later when I'm at home).
Do I have a setting wrong? And could someone try it with the same png? I used the newest photoshop.
Then another thing. Now I have this for the vmt file:
QuoteQuote LightmappedGeneric { $basetexture "de_metro/light_white" // diffuse map $surfaceprop glass // physics type }
And I make it give light using lights.rad. In game it looks like this. So it does give light. But I would like for the texture to light up as well. How can that be accomplished?
