In Max 2012 it seems this is still broken?

When I use the Pack UVs tool in Unwrap UVW, it does not add padding around the outside edge, only between the UV clusters.

But it should scale the whole pack down, so there is also some space between the clusters and the edge of the UV square.

If textures are set to tile, as they usually are, this will cause bleeding. It especially causes problems when lightmapping.

Does anyone know a solution for this? Is there a hidden setting somewhere?

An example from Don Ott’s page of the edge problem:
Pack UVs result

And here’s after manually scaling everything down a little. Why doesn’t Pack UVs do this?
Scale down after Pack UVs

No ideas about solving the pack problem?

Sorry about the size, but they’re hosted on Don’s site.

Nobody will look to the bottom of your page...it opens blank and “we” move on. Change it or don’t expect any help...and no, I can’t help with the solution, just help you get others to “see” it.

Blank? For me, large images just break formatting on the right side, so I have to scroll right to see the whole thing. Anyhow, no worries, changed them to links.

I would love a solution, or a way to avoid this, other than manually scaling down the UVs every time. Any ideas?

Ah… Flatten Mapping does it correctly, but it is the only tool that does.

Normal Mapping, Unfold Mapping, and Pack UVs all do it wrong… they add no border padding. Strange!
