NoteIf you want to transfer skin weights based
on spatial location and not UVs, then use Copy Skin Weights.
With Copy Skin Weights, your source
and target skinned geometry do not need to have the same UVs.
WarningWhen importing painted smooth skin weight
maps from a polygon mesh, the mesh’s UV maps must be free of any
overlapping UVs. Otherwise, undesired results will occur.
To
import weight maps
Select
the skin object or objects to receive the maps. If objects are parented or
grouped, select each object individually.
