Mirror only one vertex group?

Support Basics & Interface
1

Hi folks,

This is probably really simple, but…

Imagine i have a single mesh which consists of a sphere and a cube.

I only want to mirror the cube.

Is that possible with vertex groups?

I tried, using the mirror modifier, but regardless of the settings or vertex group names (.L, .R etc), the sphere also always gets mirrored.

Anyone have a suggestions? The Blender docs don’t explain it well.

Or perhaps this is better done with geometry nodes?

Thanks!

The mirror modifier doesn’t work with vertex groups.
You would need to separate the cube and the sphere into 2 different objects

OK!

So why does the mirror modifier have a “vertex group” checkbox?

Depending on what you’re trying to do, either split into 2 objects or use geometry nodes

Or machine tools mirror, works on selection

If you have a look at the docu and for example have a left side of an object and also some vertex groups named something.L (and more) then when adding an empty vertex groups named something.R the a mirror modifier with vertex groups enabled will mirror the vertex groups… but only after you applied it.
