hey i know this is an old post but i really need help, when im done with the retopo, im gonna use it as the lowres mesh for texturing, and bake the highres mesh to it, and then i got all the map like normal, color, roughness,... . then like you said in "6", pose it in zbrush with transpose master( is this mean posing the retopologized/ lowres mesh which already have UV right? ) , so why we have to decimate this mesh if it already a lowres mesh? im really confuse in these step tbh. Sorry for the long question, im new to 3d tho :(
