Having trouble porting RTB's ISM2 3DSMax import script to Blender (Python 3)

[LilacDogoo]

HyperDimension / MegaDimension / SuperDimension Neptunia
I have updated my Blender Add-On.

• Imports characters, accessories, weapons, processor units, and level maps.
  
• Supports texture maps (diffuse, specular, emission, and normal).
  
• Vertex coloring also works.
  
• Alpha blending is easily enabled.
