I’ve only been using Diffeomorphic for a little while so I’m no expert, but I’ll explain the little bit I know in hopes that it will help.
Import Character using Diffeomorphic. If using the latest build of Diffeomorphic 1.5, I uncheck the boxes. I have not figured out how to use the Simple IK yet.
After import I always merge rigs so we only have one rig to work with. Select all of the child rigs (clothes, eyebrows, lashes, etc.), select the main rig last, then hit ‘Merge Rigs’. I don’t know if it has to be done that way but it works for me.
With the base figure, we can pose individual bones, but the joints won’t look right.
So, we import JCM’s (Joint Corrective Morphs) and flexions so the joints look correct when posing (notice the difference in the armpit and shoulder).
But, at this point, we cannot import poses (some might work, but not all). We need to import Units, Expressions, Visemes, and Body Morphs. Then import a pose and it should work.
Cool, right? But now we cannot pose the bones individually. The bones are driven by the shape keys under the body morphs panel (notice the purple color in the right panel).
We fix this by ‘Add Extra Face Bones’ and ‘Make All Bones Posable.’
The posable bone layer will be in layer 8 on the panel on the right, and the bones driven by the shape keys will be on layer 32.
I think either layer will allow us to import poses, but only layer 8 will allow us to pose bones individually. Now we can import poses and then pose individual bones to get the perfect pose. For the face, we can import an expression and then fine tune it with the individual face bones.
My example was a little out of order just to demonstrate how it works. I think Thomas put the items in the import menu in the order they should be performed. So, after importing your character, make sure global settings are correct, apply the ‘corrections’ that you want to apply, then apply any ‘material’ corrections, then import ‘morphs’. That should give the best results.
If you see anything that is incorrect, please let me know.
