Baking a texture onto a high poly mesh from low poly?

Jarvgrimr

This seems like it should be doable... and it may be quite simple. 

So I have a low poly mesh, with normal maps, diff & spec all made in the ol' school photoshop / image to normal map in xnormal kind of fashion. I want to take those mapped details, and project them onto a high poly version of the mesh, to use as a base for further sculpting. Is this do-able in zbrush? Or Modo?

I am going to guess that the silence on this may mean it isn't doable. Haven't had a chance to do any research on it yet - it's for a project that is at least 2 steps away from being started at the moment. Oh well.

Just use Substance painter or other painting program to project the normal map detail on the high poly...remember to uv your HP mesh.

If I remember correctly only a height/displacement map will allow you to transfer the sculpted information in zbrush. 
Maya has a map transfer fuction and  it's pretty good, I use it all the time to transfer maps when Uvs change for exemple.
I wouldnt use baked data for a new high poly , imo by the time you have every thing transfered you might as well have started fresh

That's the same process as high to low. 
Tho you can't convert a normal map to a displacement as they haven't any depth information. Never seen convincing results. But it you've generated the normal map from an heightmap, you could use it directly. For other maps, it shouldn't be an issue.
Use the zproject brush in zbrush with high and low as visible subtools, or use any baking software, substance, maya, max...
