Hi there, i'm trying to figure out the best way to solve this, i have jacket low poly and high poly made in zbrush and with a retopology made in Maya, the thing is that there is a separate zipper in the same scene in zbrush, how can i get it to be baked in substance? it's pretty long and have 65k polys, so i imagine i have this options (jacket and stripes are the same mesh)
1 - Project the zipper over the jacket with mediocre results in zbrush and use it as a single mesh, for wich i'll need some ID map latter on to apply some different materials in substance
2 - Somehow retopologize the zipper by it's own and bake normal/displacement in zbrush, and work jacket and zipper in separated scenes in substance each with their own maps.
3 - i think this is the way but don't know how to do it, make low mesh jacket in substance get baked high poly jacket-zipper details as a single mesh, btw the zipper have no UV so far, will this bring some problem when trying to bake high to low?
