EA cas replacer, mesh is stretched in game & black lines

You have more meshgroups and in different areas. If the original is in the leg area, yours must be in the leg area as well, the same area.
- clone GP02BathrobePlush, export the blend, open;
- rename each meshgroup to the last digit of its cut number, so 1, 2, 3, etc. Then hide all but the first one;
- in a separate window open your blend, rename meshgroups the same way ( the name does not matter, you do not need to give them s4studio_mesh_ before import). Hide all but the first one;
- compare each meshgroup to the corresponding one. Once they differ ( the ones in the chest area should be in the leg area, the finger should be joined with the body)
- once done, save the blend and import into GP02BathrobePlush you just made, not the one you shared
