Transfering polypaint details

blood assassin

Hello everyone.I have a question.I have two subtools in zbrush.first subtool is highpoly model with polypaint information and second subtool is my low polymodel with uvs. My question is how can I transfer the polypaint from highpoly to lowpoly since the highpoly model doesn't have any uv.

you only need to have the lp uvwed, if you already have that export both of them and import to Xnormal. 

in the hp setting, ignore per vertex color checked on the HP only

Thanks. That helped me a lot. How can I export my highres model with hd geometry on?

HD geometry doesn't export. You need to bake it down to your highpoly from within Zbrush. If your highpoly doesn't have UVs you'll need to export the lowest subdivision to an external program, unwrap it there, and import it over the subtool to do this (ideally keeping the vertex order so Zbrush doesn't have to try to reproject all the details.) Or, you can use UV Master if you don't have too many polys on the base mesh.
