This last week I've spent time doing other things unrelated to MMD. Just sometimes important things come up that require 100% of my attention. ><
However this weekend I did decide it was time to break the model into subsets and transfer it over from Maya to 3d Max. There I carefully go over every inch of the model fixing subsets/vertex normals. Once I'm happy with it I exported it to PMX.
Now I have to make sure the scale of Rin compared to other models is correct. After that I can clean up the file and name things correctly. Assign stencil color if I want to and sort out draw order on parts of the model that have transparency. Then it will be time to rig and do facials. Followed by physics and then I'm done
Sounds easy right?!
