I have used zbursh for a year now, so i know my way around it kinda. Recently been trying to get a high poly model into a low poly form to export to another program to render. I know how to get my high poly model down to export but do i take the displacement maps, texture maps, uvs from the high poly model and use that on my low poly after export?
lets say my sculpture is done and it’s about 2.5 million polys. what i do is make a duplicate. zremesh it as low as possible while still keeping the over all shape. then i subdivide that mesh up to about 2.5 million polys. then i project the detail from the original to the duplicate. after i do that, i bring it down to the lowest subdivision level, unwrap it and make maps.
that duplicate becomes the finished result. the lowest subD is my low poly version and the highest subD is my high poly version.
so you’re saying you end up with 2 models that are both 2.5 million polys and both have subdisions on them. The only difference i see is that your low poly model now has better poly flow. couldent i just use the lowest subdivision of the high model with the same results?
sorry i was thinking about your title and misread your question. i didn’t realize you were asking about how to use the maps after export.
not sure i can help you with that.
If your mesh already has subD levels and UVs you bake all of your maps at the lowest subD level, except for your polypaint, that should be created at the highest level.
Then you simply apply those maps to the proper nodes inside of your renderer of choice.
