I'm using RizomUV 2018.0.141 and I'm trying to freeze existing UVs so I can pack some UVs into the spaces that are there.
I tried simply selecting the new shells and packing (both P and Shift+P) and this doesn't work because all of the shells move a little.
I tried to 'locking' the existing shells and the shells all still move when I pack the new group of shells. The new shells go into the holes properly (think long, thin UVs) but all of the shells move.
Any idea how I can get this to work?
Recap; I'd like a way to freeze the existing shells, pack new shells into the holes (with spacing I specify) and go from there.
Okay, I found the 'Autofit' button. Problem solved. All I had to do was uncheck this, lock UV shells, and pack other UVs to fill spaces. Trouble is that now the new UVs aren't packing into the same 0-1 space. Some of them are going to the another UV box. This had something to do with my default spacing (set to 10). Reducing spacing helped with this as the program was able to pack more in to the 0-1 space without moving or resizing everything. The last few I could place by hand.
