So- I am trying to transfer a texture to another version of the same mesh. The UV map is EXACTLY the same, no edits or anything, it is only the mesh's shape that has been changed... yet, no matter what I do- whether it's importing the other mesh version into the same Substance file, or trying to use a smartmaterial in a new file, the texture ends up completely warped and incorrect.
I need a way to get the textures to match up TO THE UV, not the mesh, because the brush strokes no longer match the same way on the mesh because it has been edited... but since the UV is the same, the textures SHOULD be able to apply to the mesh just fine. Yet for some reason, it always seems to go off of the 3D object instead of the UV when applying the textures. How do I fix this??

From what I understand you have gone back and changed your model and want the textures you already made to apply to the new model?
What you have to do is go to edit > Project Configuration > File and select your new model, make sure preserve brush strokes is checked, then bake your mesh maps and you should be done.
If you need any help feel free to ask.
Yes, I want the textures already made to apply to the new, edited model without the textures breaking because the projection is now inaccurate. I want it to apply textures based on the UV, not the mesh's shape.
For example, say I have a general canine model fully textured... it looks like a wolf. I edit the model into a fox, with different proportions, but the same UV. I want to be able to import that new model, or transfer the textures, without the textures breaking due to the new proportions.
From prior experience, it makes no difference whether "preserve brush strokes" is checked or not, the texture always breaks due to trying to re-project onto the 3D model instead of just matching to the UV like it should.
Also, the advice you gave actually doesn't work at all period for this file... it just says "file import failed, reverting to previous version" and nothing changes.
Sorry to hear that didnt work.
Is there any chance you could send over your substance painter save and both models?
This has been happening with me as well.
I'm trying to swap the mesh with a more updated one and the little details are broken on the model when I do so. It doesn't give me any warning or error when I import the new mesh, painting just gets messed on some parts (especially the eye/face)
Can you send the files over?
Also did you uncheck "auto unwrap UV"
THANK YOU! Really helped me a lot! god bless you!
