Hello,
I’m looking for baking the details of my high mesh sculpt into my low poly model. I bought this model on Daz and the body was already unvrapped but with UDIM so I decided to use this addon : https://blendermarket.com/products/udim-baker but despite the help of this addons I don’t manage to bake the UDIM of my low poly to my high poly, how can I proceed ?
nobody know 
?
I don’t actually know about UDIM workflow, but if what you want to do is redo a UV map and want the old textures here is what I usually do.
Make have model both old and new UV maps. Plug one of old textures into emmision slot using old UV map and bake it into new UV map.
Here is something similar https://blender.stackexchange.com/questions/15510/possible-to-bake-texture-to-new-uv-map .
Alternatively I think you can use UV map node in newer versions for this.
Thank you for your help, I will try your solution !
