Playermodel: Risk of Rain 2 Titans

I have the models for the Risk of Rain 2 Titans, here, but I don’t know how to rig them to the Tower Unite Rig. Also I don’t know how to color them (brown/gold depending on the titan) or apply shaders to make it look like its from Risk of Rain 2. I was wondering if someone would be able to rig them for me? Thanks!
