I work a lot with photogrammetry cleanup and I like how zremesher works with some areas, but not others (eg: edgeloops around the eyes and mouth). Is there a way to manually retopo an area and then have zremesher do the rest. It would be amazing to only manually retopo some prime areas and let zremesher handle the rest.
Yes you can do that by hiding the areas you have re-topoed and using the Freeze Borders option.
I will try this out thank you! I am assuming this will work with a partial retopo’d mesh brought in from Maya as an FBX or obj?
Should do, yes.
I have been messing around for a little bit with this, and I think I must be missing a step or misinterpreting something. I created a manual retopologized “mask” of the face, and brought that back into zbrush. So I have the head as one subtool and the mask as another. From reading up on the freeze border it seems like the retopo’d part would have to be a polygroup of the head to be able to have it work. Is there a way for me to bring the retopo’d subtool as a polygroup into the head subtool, or copy the head into the retop’d subtool? Thanks!
Are you just doing a partial retopology and leaving the rest of the head non-existent? ZRemesher doesn’t work that way - it needs an existing surface/mesh in order to remesh. In other words you can’t just import a strip of polygons for the eye / mouth loops and have it automatically connect them into a head. You would have to take an entire head, manually retopologize those areas (the rest of the head’s polygons can be a mess of triangles, spirals and terrible topology - the key is that they’re still there and still connected to your nicer loops). Then you can polygroup and hide your nice edge loops, and have zremesher re-do the visible group so that it isn’t quite so messy.
Yes, I was mostly curious if there was a way to do it from the strip method instead of having to do the entire head. I wasn’t sure if that was a possibility.
