Retopo game model in zbrush

ZBrush Usage Questions
#1

I just want to confirm that there is no good way to actually zremesh a high res model then modify it’s edgeflow inside of zbrush. I really like how easy it is to use zphere retopology I only wish you could do that to a zremeshed subtool and don’t have to start from nothing. This would speed up retopology a lot, you just zremesh it and fix all the small errors in the zremeshed object.

But as of right now I think that the best way to retopo a model using zbrush is to export the high res model, import it into an external program. Zremesh a copy of the highres model inside of zbrush, export that and import it into another program then fix the topology in that program.

It would truly be amazing if they would make it possible to modify topology inside of zbrush.

Edit existing topology with zsphere:

Go to a zsphere
tool>Topology>select topo (the one we want to edit)
Now go to append in subtool menu and append the same subtool. This will create a reference under the editable topology of the original mesh.
Now tool>topology>edit topology with zsphere active as subtool
When finish make adaptive skin

There are more ways to do this:

Also keep in mind that you can edit topology with Zmodeler but without snapping on the original model.

I think I’m missing something, I have zremeshed an arm and I have come this far. Now what am I supposed to select and edit?

I guess this is your problem:

Edit EXISTING topology with zsphere

· Go to a zsphere
· tool>Topology>select topo (the one we want to edit). It must be the active subtool of another tool. Otherwise you won’t be able to pick it.
· Now go to append in subtool menu and append the same subtool. This will create a reference under the editable topology of the original mesh.
· Now tool>topology>edit topology with zsphere active as subtool
· When finish make adaptive skin

But as I said there are multiple ways to do the same, this doesn’t make it less confusing

(deleted the second link of my old post a it was not relevant)

Ok it works but it’s very unintuitive that you must duplicate the entire tool just to be able to select the subtool that you want to edit, but thanks this will be useful. :smiley:

#6

Zbrush is not a intuitive program. In any case you could have avoided the problem if you have not started appending the zsphere you want to use in the subtool you want to edit the existing topology. That is OK only if you want to create a new topology, but not if you want to edit the existing one. At the end anyway you will duplicate the geometry as you need to append it to the zsphere but not vice versa.

#7

For any people who stumble upon this in the future, you don’t have to save the tool just click copy and a copy of it should pop up and then you can select that from the topology window.

#8

Or append it to another tool or clone the tool. Save and load was never needed as all these operations will duplicate the subtool.

#9

Yes my bad not copy, clone the tool.
