iv created a uv map with an alpha layer, and followed the following tutorials workflow:
but im getting strange artifacts in my transparent layer see image 2
so what I did is deselect col- under mapto in the materials panel to see what would happen, and I get (image1) the alpha works perfectly
but when I select the col button I get strange white pixels everywhere, that even reflect as white shadows?
iv checked that those areas are completely transparent in the photoshop file, and not maybe a little gray, and they are completly transparent
what could be causing this
