I made this to speed up importing my sculpts into Blender for rendering. It automatically sets up materials with vertex color attributes and does a little custom decimation. I find it handy. you might too.

This Blender 2.80 addon can import multiple polypainted .fbx files from 3DCoat, Medium or Zbrush at once.  All vertex color attributes nodes and links will be automatically set up.  An optional decimation modifier can also be applied to each mesh.

note: depending on your file size, the import and decimation can take some time.  (~20 million polygon meshes take time to process)
