I'm still learning blender 3d so I'm sorry if this is hard to understand.
I'm trying to edit the stroke/textures on the freestyle editor so where it looks hand drawn/sketchy I'm hoping to get some result like this https://youtu.be/5jZvFuaNNlY but I'm still new to blender and I know nothing about textures.
I heard about uv mapping but I don't know what to do with it when it comes to freestyle lines.
