ZBrush Usage Questions
#1

Note: My worflow goes between zbrush and blender, I don’t have 3dmax.

I am trying to make a low poly model with a lot of detail both on its diffuse and normal maps.

What I do is divide the model to about 3 million polys, sculpt it, paint it and then export the maps. The problem is when I go down to the low poly version the maps stretch oddly at places, thus not looking great.

Is there a way inside zbrush to retopo the model and transfer the diffuse map, so I can still ensure a low poly model but also have a high detailed diffuse that fits the model better? Or is there other tricks that work to get the diffuse map to look good at high and low polygon levels?

You can try xNormal which is free!

  1. Put some Uvs on your hi res model and paint it. The UVs don’t have to be great
  2. Create your lo res model with good UVs.
  3. Load the hi res into xNormal. xNormal has a place to load your base texture to bak.
  4. Load the lo res into xNormal
  5. Under baking options in xNormal, check the Bake base texture.
  6. xNormal will bake the texture from the hi res (with crappy UVs)
    to the lo res (with good with good UVs)

This is a really basic explanation and you’ll have to do a bit of studying of the xNormal procedure but it does work.

Good luck.
