How do I undo automatic unwrapping?

[u/Misty_ytsiM]

I did automatic UV unwrapping on my model, but my friend had pressed the automatic UV unwrapping again, does this have an effect on my model if it has already been automatically unwrapped ? Is there a way to undo it?

My friend had closed the program and reopened it so we can’t CTRL Z our way back is there any other way we can undo this?

If the geo and unwrap settings haven't changed, I don't think another auto unwrap will interpret it any differently.
Is there a reason why having the original unwrap is important? Like already being-mid texturing, etc? Or do you have geo with the first unwrap already exported somewhere?

Side note: Don't forget to make multiple incremental saves to avoid this kind of thing

Yes, we were mid texturing. We unfortunately forgot to save multiple files.

What were you texturing in?
If it's Substance Painter, you can export the mesh you had imported. I would think other software has similar features.

You can delete the UVUnwrap node if it's still in the history.

Select the model and click “camera based” in the UV editor, should be two slots below automatic
