So I’ve been working on a drawing and I wanted to know if there is a function that you can do so when you activate it it makes it so you can only draw on areas that have already been drawn on, kind of like Paint Tool Sai’s preserve opacity feature I guess(If you know what I am talking about). This would be really helpful for things like shading. If anyone knows a feature that I can do that would help then tell me please.
Set the ink type to “Lock Alpha”.
It worked, thanks a lot
