Blender: Voxel Heat Diffuse Skinning 2.79

Traditional heat map diffuse skinning algorithm can only deal with watertight meshes, but artists create character components in their own way, then group them together to a character, usually the character is not seamless, this often cause traditional heat map diffuse skinning algorithm to fail.

Voxel heat diffuse skinning algorithm can overcome the shortcoming, it converts the non-seamless character into a solid statue, heat diffuses in the solid statue, so we can get the most natural vertex weights.
