From High to Low Poly "zremesher"

David1983 · Jan 2015

hey folks
Can someone expalin to me the worklow of going from a high poly mesh to a low poly mesh in zbrush. Basically in know how to make the low from the high poly but what about the texture? The texture is aligned to the hp mesh, will it fit also on the lp mesh after using remesher? the uv'swill be the same?

Do you mean a bitmap texture or Polypaint? You can project Polypaint from the high onto the new low mesh but the UVs are destroyed when using zRemesher.

I have full UV unwrapped HP mesh with a diffuse texture on it... Bascially i would like to create now a low poly version of this mesh... but i have no idea how reuse the existing diffuse map which is alligned to the HP mesh...

As long as you UV the model after retopologizing it, you can bake the texture from the highpoly model to the low poly model regardless of how different the UVs are (in fact, the highpoly model doesn't even need UVs if you're using polypaint).

The important thing is that the meshes' geometry occupy the same space. Then any baker can pretty much do the transfer for you. Here's an old xnormal tutorial that shows transferring a textured highpoly's texture to a new lowpoly mesh:
