[V4.5 BETA (experimental)]

I think you'll find that when you use copy/paste UVs with more distinctive topology 3D Coat does a better job of stacking them correctly.

[Where can I download old versions for Linux?]

I want to download the last version of 4.1 but all of the downloads are for Windows. If someone would make the Linux builds available at some point, I would really appreciate it. It's not super urgent because I can just boot Windows, but it would be nice if you've got the builds around somewhere to have them available for download.

[Help with UVs, Mirroring, and Packing]

Thank you. It does seem to rotate it in some cases... is that particular algorithm allowed to rotate an island in non-90-degree increments for even greater UV optimization?

[Help with UVs, Mirroring, and Packing]

Is there a way to pack mirrored UVs with rotation and scaling but without un-mirroring the UVs and making them unique? I know you can make correctly mirrored UVs with Copy and Paste UVs, but it looks like there's no way to pack them without rotation that makes all the UVs unique, and I'd love to be proven wrong.

 

It would also work out OK if there were a way to pack just selected UVs, because then I could just move one mirrored half off of the UV space, pack the UVs that are still on the 0..1 UV space, then copy and paste the other islands back.
