??? Uvs to transfer from lo to Hi res??? Any pointers for us out here?
The reason your char was flipping when you tryed to overwrite uvs could be a max prob, it can rewrite the vertex numbering on export of obj, that’s why things sometimes get messy in higher subd levels.
Zb3 flips models and normals on import so you may wanna try a combo of rotating your model and flipping the norms before you export from max.
What I’ve often exported an obj to ZB2 (hi res) and reconstruct subdiv to base level so that I can run the pipeline back to Max from there…
Hope that gives you some more options… Wrap deformer can be pretty unstable
