Very often when i finiSh working on UVs and textures for object, im being asked to edit uvs and textures. So what would save me a lot of time, would be if there was an option to move the island together with texture assigned to it. Is there an option to do this ? How you guys deal with fixes like this?
Let's say You have Susanne:
If you want to move her eyes, you can load the texture in a 2D program, e.g. Photoshop, select and then move the the eyes like so:
Write down the offsets:
795.05 - 903 = -107.95
395.45 - 301 = 94.45
Divide these offsets by width/height to normalize them, and flip the Y coordinate (because in Blender Y rises up, but in Photoshop it rises down):
-107.95 / 1024 = -0.105419921875
94.45 / -1024 = -0.092236328125
Load the new texture and move the islands by those numbers:
I found an easy way to bake a new texture :D that solves my problem!
Which is a perfect solution for me. This is link to tutorial on how to bake a new texture after you changed up the UV's. Tutorial: Possible to bake texture to new UV map? This is solution by gandalf3♦ oryginaly a reply for diferent but similar question.
