Hi guys,
I forgot to create uv map for my base mesh and now, my sculpture is in its highest subdivision level and all other levels have been deleted. I have also done decimation process over my model. I’m going to do some texturing in substance painter but I’m losing uv coordination. Can anybody help me?
You can import you original UV’d mesh back into Zbrush
append that to your mesh and subD that mesh, then project all of your details from your broken mesh onto the one with UVs.
If you don’t have the original UV’d mesh or at least a backup of it somewhere then you’re going to have to either rebuild your lowpoly again and unwrap it, or try to unwrap your decimated highpoly.
Good luck.
