I apologize if I disturb such a fool. It is a doubt that I cannot resolve.
By necessity I am using 2d software, PScs6.
Now, I've downloaded a lot of brushes, and they all seem to have the same "flaw". Obviously it is not a defect I am not understanding the use. If I need a DIRTY brush for example.
I download the brushes but when I use them I have this problem. no alpha channel on brush.
The brush is a SQUARE shape and is usless for me for add some dirt to my textures, etc..
I notice that only a few brushes around (I assume not HD) have alpha.
What I ask is how do I then use these brushes if every time they leave me a SQUARE shape, on my sheet? Thanks.
