You can transfer vertex positions, UV sets, and vertex color between meshes with identical topology (generally, meshes that were created by duplication).
Select the source object and the destination object, in that order.
Select mesh > Transfer > .
Choose the type of information you want to transfer (Vertices, UV Sets, Vertex Color), then click Transfer.
先选择 源对象(有UV信息的物体) 再选择 目标对象。然后执行该命令 mesh > Transfer
mesh__Transfer Attributes
应该不能删掉原模型吧,
两个模型一样的情况下,mesh下 transfer attributes 调一下数值应该可以了
