Texture Painting Transparent I have a problem with texture painting in Blender. 
I can't seem to get the transparency to show up in the viewport. 

I have made the material transparent. Painted the texture. 
But it just appears white like here.


But I'd like for it to actually be transparent in the viewport.
GLSL is active too, btw.
You can do that in GLSL Textured Viewport Shading

First open material tab, enable Transparency and set Alpha to 0



Then open Texture tab, select the texture you are painting on and in Influence section enable Alpha
