I know I shouldn't blame blender for this, but it's not like there's a blender_mmd_tools stack exchange. I don't know a better place to ask.
When I upload a pmx model, there doesn't seem to be an armature. At least, I can't see one on the 3D view. It's visible on the outliner. It seems to have all the bones. But when I select it on there, I can't change the 3D view to edit or pose mode.
Has anyone else had this problem? Should I try an older version of blender? An older pmx model?
