Shader access to alpha channel.

b1s · 07-08-2011 08:12 AM

I'm not sure why I'm not getting this to work..

Im trying to get access on the alpha channel of the material I'm using for the object. For some reason I cannot get it to work.
What am I doing wrong here?

Vec4 col =Tex(Col,inTex).rgba;
return Vec4(0,col.a);

if material has base_0 and base_1 textures, then alpha (opacity) is stored in different place
Tex(Nrm,inTex).z
