Video game character creation pipeline

a1s

Hello. I am new to everything and I was wondering if anyone could answer a few questions. I created a character sculpt in zbrush. It is high poly with 2mil points. After that I retopoed it down to 2k points. Now I have 2 .obj files. High and low poly. I assume that my next step is to create a UV map. Do I need a UV map for both meshes or just the low poly mesh. Not really sure where to go from here. My end goal is to rig it and import to unreal engine. Thanks in advance for your input.

You only need UVs for the lowpoly model.

Thanks PolyHertz. That helped me. I do have another question if you have a chance. I imported my model, texture, normal, and displacement map from zbrush into ue4. I got everything to display properly except for the displacement map. Do I have to use a bump peramater or tessellation? Thanks in advance.

For video game character creation zBrush is super for making hipoly characters and painting skin textures. For the other work like making a low poly version and baking the other textures a standard 3d app or dedicated texturing app is best. Displacement maps are used in films in combination with a subdivision modifier as far as I know.

Games don't use displacement maps on characters. It would be way to expensive.
