The right one is the sculpted version, the left one is the retopologized version, quad only. So and now I have no idea what to do next exactly. I first tried to paint the texture on the low poly version, but then I remembered I somehow need all the maps from the sculpted version, and when baking, this happened:
I added the normal from the sculpted version to the retop-version. I suppose I also did the baking wrong. When you are at this step at character creation, meaning that you have 2 models, one retopologized and the sculpted one, do you draw the textures on the high poly mesh or bake something else and draw on that? What would be the next step in a character creating process?
