I want to just 2 objects have some UV coordinate...

OK, the command like "copy mesh attribute' can send a UV set to another mesh
But, it's just a copy, I want to 2 meshes are connected with UV set.

I tried some ways, but I couldn't get the one.
Is it impossible?

I tried, and failed. I could only do it if I hooked up every UV individually, but that's not feasible.

Hi H.Kim
i tried the "copy mesh attribute" with the "UVSets" checked in the option box. It creates a polyTransfer in the history , which does allow you to change the UV´s in only one object , affecting the others. Isn´t that enough?
