Zbrush - imported UV map/displacement map bake issue

iniside

I have simple mesh.
I first used UV master to create UV on it, and then exported mesh, to external map for further tweaking (seams).
After that I imported the uv maped mesh, and used UV master to copy UVs from imported mesh to my original sculpt
This is how UV map supposed to look:


And now simple displacement bake:


I think you can clearly see what's wrong with it.

When I use UV map generated with UV master, it all work fine, and displacement bake look fine (even though it's bit distorted because UV master can't create seams where I want it to).

You shouldn't need to copy and paste uvs. If you import the new uvs they should update automatically. If they don't, it means your vertex order has changed (in which case copying and pasting with UV master will mess things up).

Generally you want to export a single polygroup to prevent this ( which means turning GRP off in the export options). But if you are using max to edit the uvs, it has a nasty habit of disconnecting and flipping them. Goz instead

Thanks!

Using GoZ solved the issue, whatever that issue might have been.
