Smoothing border edges

ZBrush Usage Questions
#1

Hi!

What decides if you can smooth a border edge or not? (smoothing with the regular smooth brush)

Cheers,
Asbjørn

Do you mean an open edge, I mean a hole in the mesh or simply an edge of the surface, for example a 90 degree angle?

#3

Yes. A hole in the mesh, an open edge. :slight_smile:

In an open edge of a hole

Using smooth in an open edge Zbrush will hold the verts that are in the edge to avoid overlapping verts.
Alternative smooth without pressing shift is a bit stronger but doesn’t change it.

In brush->Smooth brush modifiers->Min connect set it from the default 3 to 1

Now smooth again. The edge will now move but the topology will be messy with lots of overlapping verts.

Thanks for your reply Altea! I still get different results on my subtools regardless of the smooth brush settings, any ideas?

Demonstrated in this video:

aslo:
nothing is hidden on any of the subtools, so they are both indeed border edges with three edges running into each vert. :slight_smile:

thanks!

Can I share that grey geometry?

Here’s the two subtools. One with smoothable bordere edges, and one that won’t.

The reason of this odd behavior is because you have applied a Dynamesh over the mesh that can be smoothed the edged but it is not active. If you drag with control in an empty part of the canvas you will see Dynamesh converting the object.

If you want to make this unusual behavior to disappear simply deactivate dynamesh button and use the system that I said with the brush setting when you want specifically smooth the edges.

Great! That explains it. Thanks a lot :slight_smile:
