"I like anyone who uses many app to get the final image"

I downloaded Zbrush and played with it for while
from the first time i knew this app will be something superb, it is different from any app i tried before
It is not easy to learn, it is not or does not have the graphics standard

For ex. After importing a psd file with Layers(channls), i could not use or color each layer (channle)seperatly, then composite them, When i mean coloring layer i mean that they should be treated as masks, color only inside.
If you have any info regarding this it would be nice if you pass it to meeeeeeeeeeeeeeeee.)
