Project all advice for 3.5?

ZBrush Usage Questions
#1

I’ve been trying to project a sculpt of mine onto the retopo’d mesh of the same sculpt in an attempt to kill some of the pinching I’ve been getting with the unified skin meshes.

I can’t seem to get anything to project onto the new mesh however and the few times I have it destroys a good portion of the new mesh as well. I’ve tried tweaking the PA dist., and while it was the only way I could get some success with the projection it also always destroyed parts of the mesh as well.

Anyone have some pointers for me so I can figure this out? :smiley:

#2

Screen shots of the problem would help.

#3

This is the kind of thing that’s going on, but for the most part whenever I try to project all nothing happens at all.

This is a pretty extreme example because I just used a sphere on the dog, whereas the model I’m working with is literally a retopo of the same model. It’s doing the crazy distortion mostly around the legs, but not necessarily restricted to the area.

it seems like 90% of the time I can’t get “project all” to do anything, and when I do get it to do something it just stretches really bad or breaks the model like in the picture.

Perhaps you started off too small and it’s throwing the software off. Try using the Unify function on both the original mesh and the retopo. You may need to use Transpose to realign them afterward. Once they’re unified and aligned, try Project All again.

#5

I’ll try unifying them both and see if that works.

Just curious though, what do you mean by starting off too small?

edit: unifying the meshes didn’t help, it destroyed the mesh again like above.

#6

Are there holes in either mesh? Are there cavities that might cross geographic center of either mesh?

These can throw the projection scan off.

(The best fix is make super-deep cavities less shallow for the projection and then re-deepen them afterward.)

Also, check for any criss-crossing or overlapping topology in either model.

I retopo’d the model in a different software package and imported that in this time, and it worked perfectly. I may have screwed something up somewhere in the retopology in zbrush, which seems pretty easy to accidentally do.

I love zbrush, but I loathe it’s retopology tools.

#8

I use Topogun myself. :slight_smile:
