Mesh support mirror (symmetry) on all axes
Confirmed, NormalPublicTO DO


Currently symmetry is hard coded to X axis in many places.

Symmetry on any other axis isn't possible, this task proposes to support symmetry on all 3 axis.

This impacts:

  • Transform
  • Weight Pain (see T65872 for why sculpt symmetry isn't appropriate).
  • Edit mode smooth.
  • Particle editing.
  • Armature/Rigging (need to look into this)

Weight Paint

As far as I can tell, the Symmetry options in Weight Paint mode work perfectly on all axes. It even has radial symmetry, which also appears to work. T̶h̶e̶ ̶o̶l̶d̶ ̶X̶-̶M̶i̶r̶r̶o̶r̶ ̶o̶p̶t̶i̶o̶n̶ ̶s̶e̶e̶m̶s̶ ̶r̶e̶d̶u̶n̶d̶a̶n̶t̶,̶ ̶a̶l̶t̶h̶o̶u̶g̶h̶ ̶I̶'̶m̶ ̶n̶o̶t̶ ̶s̶o̶ ̶s̶u̶r̶e̶ ̶a̶b̶o̶u̶t̶ ̶T̶o̶p̶o̶l̶o̶g̶y̶ ̶M̶i̶r̶r̶o̶r̶. Nvm I'm dumb, X-Mirror != Symmetry.

does this task also affects the mirror vertex groups in the mirror modifier? or is that a completely independent topic?

I want to point out a limitation of the symmetry tools in Blender.

For meshes you can't mirror editing using various tools like extrude,bevel...etc only transforming the components of the mesh.
but armature bones can be extruded so in a sense it's inconsistency...... is this something that will always be like this or the limitation can be lifted with the addition of the tool system?.
