Optimize UV map after removing geometry I have a model created via photogrametry. I removed lots of unuseful geometry, but the UV map stays the same, taking a lot of space containing non useful data. I need to optimize the model for the smallest possible size.

Is there a way to optimize the materials so they're only made of the remaining part of the geometry?

Thanks for your help
I never did this in Blender, but the way should be like this:

1.) Make a copy (not instance) of your mesh

2.) Reunwrap the copy(its probably easier if you turn off the textured mode while doing that)

3.) Bake the texture from the old model to the new one. I googled this here
hope its still valid / useful
