I'm wondering if anyone's come up with a good workflow to take a model from Mud to ZB for Transposing and then back to Mud whilst retaining the original levels in Mud. Possibly a method that dosn't rely on "sculpt using displacement" but rather on layers.

cheers.

I tried posing a while back (not in Zbrush though) by using import as layer and bringing in a posed version of the base mesh. But the higher layers seemed to get screwed up. It looked like the verts are stored as offsets in world space, so all the detail went off in the wrong directions once the limbs were posed. Don't know if there was something I did wrong, but it didn't seem to work for me.

Is this the sort of problem you're having?

Well,i havn't really experimented yet but i was thinking it'd be great to take advantage of Transpose in ZB instead of having to rig characters for stills.being able to sculpt in a base pose to a certain point and then transposing for final detailing would be pretty handy. I don't like relying on "sculpt from displacement" as i havn't attained 100% accurate results so far.

to reimport from zbrush is use import as layer with use of uvs... and it works fine...

Cheers Christoph,i'll keep trying it.

ZB uses a different subdivision algorithm than MB and hence you end up with a different vert ID set on higher levels, so as long as you dont subdivide you should be fine reimporting the same exported level as a layer via point ID's back into MB. Via UV's does not yield clean results on higher-res meshes according to my experience and I would not recommend it.

Also, reposing of lower-res meshes does not transfer too cleanly onto higher subdivs in MB and creates all kind of weird distortions on the high-res sculpt especially fingers etc.

Export your high-res MB sculpt into ZB as an obj. Recreate the lower subdivision levels and pose the mesh as desired. Take your Transpose-posed ZB mesh on the lowest level into MB and subdivide it up to the high-res ZB equivalent. Import that into ZB and append as a Subtool to the posed ZB high-res tool, "Project All" to transfer the higher-res detail to the newly appended high-res MB mesh, then re-import that into MB as a layer via point IDs. You should now have all the levels back in MB. Although "Project All" is pretty good, some clean-up work in tight spots is to be expected.

Hope this helps.

Cheers!

if you use z only for posing it works fine to import with uv use...
cause you dont need a really highres mesh... level2 should work fine...

Thanks for the advice lads.I had some pretty good results earlier exporting a mid level mesh> transposing and importing as a layer.It's good to know that it's possible.

cheers.
