I have attempted to use Dirty Vertex Paint, but the issue I have is that it seems you need a lot of vertices to make this work effectively, thus increasing the size of your model and slowing down Blender. Is there a way to get good results with Dirty Vertex Paint without having to sub-divide your mesh? I’ve read something about making a copy of mesh, sub-dividing, then applying, then use Dirty Vertex Paint, then bake, then deleting sub-divided mesh and applying baked to simple mesh…but that seems like a whole lot of extra work just to get some dirt.
What is the best method for this? And if the “bake” method is best, are there any good tutorials on this?
