I’ve noticed in the 3D View, when I’m in Edit Mode with a particular object (which was created by mirroring the object along the X axis), the Y axis mirror icon is purple…or if I click it, it will switch to dark blue:
From a user interface perspective, what does this mean? It seems that if it’s not possible to mirror along the Y axis, the icon should simply be disabled, not a purple or dark blue color.
When I hover over the icon, the tooltip gives me “Expression: var + False”:
Hovering over the X and Z axis mirror icons do not show “Expression: var + False” in the tooltip.
It’s fine if I cannot mirror this object along the Y axis, but I’d really like to understand what these two button states (purple and dark blue) mean on the Y axis mirror icon.
