Dynamesh subdiving way too much.

ZBrush Usage Questions
#1

So I’m running into a problem that when trying to dynamesh an object it, just gets extremely dense.

The scale of the objects I’m working on is fairly large and, since they are for a game environment, they need to be offset from the center of the world but I only run into this issue with certain meshes.

Right now I’m even just importing a zbrush default cube and still get a crash when trying to dynamesh it, even with the Resolution at 32 or 16.

Is the density based on the bounding box? Is there any other scale element involved? Is the center pivot relevant?
Any help would be very appreciated!

Density is based on the size of the mesh. Too large and even minor resolutions will crank out dense meshes. Too small and a high resolution doesn’t produce much. You get closer to the ‘goldilocks’ zone the closer the mesh is to being unified (tool: deformation: unify).

Thanks for the reply. Unify doesnt really do the trick it just resizes the mesh making me lose the original position on the 3d package.

I ended up finding this thread that gave me the solution!

So I guess until Zbrush 5 this will always be a problem:

You are right for what you are describing, ZBrush doesn’t like massive files. That’s why we have the Unify command in the Tool >> Deformation palette to “reset” the files transformation information.

We are thinking of adding in GoZ a scale I/O factor for the target application and make such behavior disappearing. But unfortunately, it won’t be possible before the next major update of ZBrush (5)
