Hi @Yeehawcowboyletsgo – lots of answers above already! Short answer – yes you can. Here is the slightly longer, more complicated one:
While Grease Pencil *can* be used to draw directly onto a surface, it is not like texture painting. In fact, a grease pencil object has dimension. So you’re gonna get some unwanted results.
The advantage of using Grease Pencil is that it is more like vector drawing: you can render at any resolution you like without quality loss, but once that render is baked, it is a bitmap – just like anything else you’d render out of a 2D drawing application. So yes, I would use it in a similar way, but I’d render out the product and use it as a texture after.
The alternative to what you are suggesting is to simply use the texture painting options inside of Blender – this will allow you to do what you’re thinking dynamically, and directly.
