Hello everybody, a few days ago I've released my script for MAYA, which helps me a lot when creating UVs. I thought somebody else might find it useful as well.
It can help with packing for UDIMs, can check for overlapping amongst many other things, rectangulate, straighten uvShells quicker and on a different way than the current tools in MAYA, and there's many more stuff in it. So if it sounds interesting to you, please take a look at the trailer. And also, please do let me know your thoughts.https://youtu.be/dImhT9CLNB0
It possible to pack with UV groups (you call this transform proxy ?) or mesh element groups ?
And if in addition it's possible to freeze a group size that would be some great additions.
@walter -It works on somewhat different principle than what you described. The Transform Proxy is not related to the packing function. It is made so we can move scale and rotate large chunks of UVs without selecting the UVs.
For packing you have a bunch of options, freezing is something I was considering, but seemed like it would overcomplicate things. But the distribition and layout can move entire groups together without changing the layout inside the group, I guess that's the functionality you are asking for. There's a longer video on youtube where I explain everything. It's 20 minutes long, but I tried to make it as time efficient as possible. Jump to the distribution and layout section to learn more.
