Zspheres amount of loopsr bone - can we reduce it?

ZBrush Usage Questions
#1

In our studio we are currently using ZSpheres - Adaptive skin to create custom tree trunks + branches for a realtime engine since its the best workflow we found so far.

The only problem we are having is that we can’t find an option to reduce the amount of loops we get for each Zsphere “bone”.

If i can change the mesh density using the G Radial wouldn’t it be possible to also have the control for the amount of loops between bones or at least define a percentage for them?

Here is an image showing the issue

Because of this we need an extra step of removing all those loops in another 3D package making it slow to do any quick changes without having to clean the meshes again.

after you make your mesh go to
tool.geometry.edgeloop.delete loops

there are sliders to play with for angle etc as well.

I can’t seem to find the delete loops under the Edge loop tab?
These are the options I find :

Also these options seem to affect the mesh after its no longer a Zsphere so that means any reductions to the loops would not take into account the amount of loops per bone right?
On my previous images you can see that the smaller branches have a much denser amount of loops than the main branch so for this to work I should be able to do it procedurally.

delete loops came about in version 4.5 that looks like 4.4 menu ? did you try adaptive > use classic skinning and adjust > ires ?

Nevermind, just updated to 4R5, all good now! And the edge loops works perfectly! Thanks

With Adaptive Skinning, ZBrush will always try to create quads that are approximately square, so that the polygons are evenly distributed and the mesh good for sculpting. That’s why longer, narrower arrangements wil result in more divisions between ZSpheres.

Thanks for the update. The new edge loop remove tool works perfectly for our needs. As usual amazing piece of software!!
