Texturing workflow for games question...

ZBrush Usage Questions
#1

Hello,
I have a question about texturing workflow some of you might be using for game models…

Right now my workflow looks something like this:
1- Concept Sculpt [sculpt the who character in ZBrush out of rough base meshes ignoring topology and poly counts]
2- Retopologizing the whole model [with clothing] into one piece in Maya
3- Generating Normal, occlusion, and cavity maps using xNormal, since projecting the details onto the retopologized model in ZB never works properly especiially with multiple subtools
4- Texture the retopologized mesh in ZB and Photoshop…

The main issue with that workflow is that I’m texturing the low res model in ZB, it makes it very difficult to follow the details I sculpted in the high res model. I tend to apply the occlusion + cavity map onto it to tell where things were on the high res, but that is very annoying and doesn’t last long after I start poly painting over it…

so my questions is: Is there a way for me to texture the high res model and somehow transfer it to the the low res properly? or is there a way to nice project details from the high rest onto the low res other than the projectAll function?

I assume that if I texture the high res, append the low res as a subtool, enable polypainting, turn off zadd, turn on RGB, then projectAll it would project the polypaint, but I’m skeptical…

This is the concept sculpt:

xnormal can take your polypaint or texture Data from your highres sculpt and bake that to the lowpoly as well. So you get cavity, normal, AO, and Diffuse.

hope that helps.

xNormal is THE tool for this, but you can also use maya’s transfer maps to project the color/texture of an object or objects into another one.

Something very important DONT USE zBrush matcaps while texturing for games :ex: :ex:

Oh awesome! I’m hoping the diffuse transformation is as good as the other maps xN generates!

This character has already been textured, I’ll be trying this on my next one! Thank you for your replies :slight_smile:
