Hello,
I’m japanese . I’m sorry, my English is not good. MMDLoader does not deal with other than vertex morphs such as UV, Bone, MaterialMorph.
So first, I’m trying to implement BoneMorph but there are two problems:
First, I don’t know how to calculate ‘position’ and ‘rotation’ .
Second , I don’t know how to use MorphTarget to not vertices but Bone ,UV ,Material in buffergeometry.
Sry, without providing more information it’s not possible to help you. MMD related question are problematic since it is a very specific format and not widely used in the industry.
