Ok so Im working on a high poly mesh soon and my question is in regards to the end near the texture phaze what I want to do is when im done with my high poly I want to project out some textures of photo real faces onto the characters head from multiple angels, and when done export it into xnormal and bake out its high poly…
well lets say the model has no uvs , or uvs I decide to use for a different low poly when baking, If I were to just slab some GUV , would xnormal read that as verext colors being painted or as a diffuse? because the 2nd part might not work if thats the case...
You can load up a diffuse texture and bake that in xnormal, as long as your highres has uvs etc, auto uvs in zbrush should be fine. XN doesn't have any way to bake vertex colors to diffuse AFIAK.
http://www.pixologic.com/zbrush/zapplink/ should be just the thing for your first issue. will most likely require some fixing by hand afterwards, but it's really fast and quite nice. you just need to have UVs on the model, but GUV or AUV tiles from inside zbrush do work. hope that helps :)
