Does it make perfect UVs automatically?

No. It generates a starting layout that should be inspected and refined.

Does it set an exact texel density?

No. It matches relative UV scale using mesh surface area and object transforms, without a fixed pixels-per-unit target.

Does it overwrite my other UV maps?

It writes to the dedicated Seamwick UV map and rewrites that map on rerun. Other maps are preserved. Check which UV map your render setup uses.

Can several objects share one atlas?

Yes. Select multiple eligible meshes and run Auto UV to pack them into one shared 0–1 tile.

Which platforms are offered?
