OBJ to Dynamesh Errors

ZBrush Artworks
#1

Hi All

I’ve made a basic model in my 3D app but I want to carry out some additional sculpting, unhindered, in Dynamesh.

Problem I have is in the conversion of my imported OBJ, to a Dynamesh model.

I’ve included before and after images of my mesh (with the Dynamesh settings). As you can see the wings and legs have substantial errors on them.

I have tried increasing the Dynamesh resolution which helps a little but still produces a poor mesh.

Can anyone suggest any solutions?

That is a screenshot from R7. Upgrade to Zbrush 4R8. The upgrade is free for registered users, and the Dynamesh projection was improved.

Otherwise you may have to inflate the wings slightly prior to dynameshing.

Tried Dynameshing in 4R8 but still got the same errors.

I’ll try inflating the wings and legs but if anyone has any other ideas I’d appreciate hearing them

Thanks

For what it’s worth, that dynamesh is still pretty low rez. You may have to crank it up. If the object is especially small in the ZB worldspace, the values required to increase the resulting resolution also increase.

If all you want is a simple remesh, ZRemesher will probably do a better job here.

Yeah I cranked the rez up but still got a bunch of errors.

Not sure Remeshing is right for this at the moment. I just want to be able to sculpt away without worrying about topology until I remesh further down the line and then bake out displacements etc.

Dynamesh is perfect for this but its redundant if I have to start finding inefficient work arounds to get a decent start point with the mesh.

Well, both Dynamesh and Zremesh will change (remesh) the topology, but Zremesh will respect the geometry more (keep the wing surfaces separate) without needing obscene levels of resolution. From there you can always subdivde as much as necessary.

Duplicate your mesh as a subtool and zremesh the duplicate, that way you can always project anything lost back onto the duplictae from the original.

Those wings are very thin and very close together, and they will always be problematic for Dynamesh. Dynamesh needs a bit of thickness.

Thanks for the reply Spyndel

I’ll experiment with both suggestions and see if I can get a workflow going

Many thanks
