I want to make some charachters with equipment and animation 

I want to create some characters with equipment and animation clips.

I want to make a character where the different parts of his body are spread out in a hierarchy. Then I want to make equipment in a hierarchy too.

The idea behind the hierarchy of the character is so I can apply different materials to each item in the hierarchy. The individual pieces of equipment will also be in hierarchy for the same reason.

The idea is so that I can program the character to animate and display different equipment.

I want to do the modeling and hierarcy in Rhino and then materials and animation in blender and transfer it over to either unity or gamemaker or unreal.
