How do I get a texture after applied with shader?

0 votes

I want to make a coloring game, and I need to apply shader just once and then get the texture. I know I can just resize and crop the texture from view, but if I use this method multiple times, the image gets blurred because of the resizing process. And I can't get the texture alpha channel from viewport because as far as I know you can get it.
