Would love to have a blender export like you have with AE, where I can import my render into blender and continue animating with grease pencil, modifiers, and 3D things that I can make look 2D. I am already doing this, but its a work around. Would be great to have it imported into BLENDER for more 2D animation in 3D environment of blender, using grease pencil.

Or, imagine a plugin for grease pencil on blender which allows us to draw directly in CTA5, along with modifiers... would be amazing.
