Hello everyone, first please look at this illustration
Say, I have an colored model but with no shade. Now I want to create a layer with black and white shading, but is drawn by me, in order to have shadows exactly where I want them to be. Like, I draw the black on model then “hide” the model but it’s still there, then while the invisible model move, the black ink will also move since it is “stuck” on the model.
Is there any way to do that?
