here are two sets of mesh which looks identical, vert edge face count and even the vert index order are the same.
when use “transfer uv maps” from 2 to 1, 1 as active object. mesh 2’s uv is messed up. vice versa.
if duplicate them and use transfer uv maps operator on their respective duplicates, ( after altering their UVs a little bit) the results work as expected.
is there any different attribute between mesh 1 and 2? or transfer uv maps has error?
