I want to animate a few custom characters. They need to be 2D. I have all body parts individually (PNG files) parented to the 3D meta rig at the corresponding angles. I have front, quarter-turn, and side view. I wuld have no problem if I was allowed to use separate bone structures for the same character. I have been key framing the alpha fade parameters to hide unused assets when rendering. The biggest issues I have are the toggling between eyes and mouths on each character.
I have a separate rig for the mouths using UV mapping technique and sliding a bound obj over a map of the mouths. When I have 2 or more mouth rigs in a scene, the rig glitches and doesn't render. I just copy the rig when
For the eye rig, I have one asset for the different eye colors and a separate one for all the eye lids for each direction the character faces. I do not know how to set this up.
All tutorials I have access to say I must redraw all assets in Grease Pencil then manipulate them. That would work, but I already have the assets made by an artist.
I have both blender 2.79b and 2.8 beta.
