I want to create a game of coloring book.
So far I have read and researched that I have to create the asset with different parts separated in white and then reconstruct them in unity. this is good for some basic drawing with large areas.
my question is is there a way where I will just have to create a png of the drawing with black outlines. User will tap on the empty area and that will be filled with color.
please help me out here.
