unity3d - How to reuse character rig? -

i have 3d character in game , have rigged using mixamo auto-rigger. realised character had lot of polygons game. used rigged fbx in maya , started trimming polygons. , when re-imported same character rig not work , when go rig tab , select configure. bone seems out of body reason.

please tell me i'm doing wrong here. , right workflow export rigged character maya? don't wanna pay $79 dollars 1 time again rig same character through mixamo.

-change polycount(retopo) -import new mesh (tpose) in rig scene(highpoly) -select highpoly mesh , open "paint skin weights tool" -select joints in list -select in mode "select" / have skinned joints -select new mesh , skin / "smooth bind" -go "edit smooth skin" , "copy skinn weights" highpoly lowpoly mesh
