I have something like this:
Suspension (Object)
|-- LeftWheels (Group)
|-- Wheel 1 (Object)
|-- Wheel 2 (Object)
|-- RightWheels (Group, created by Mesh->Mirror, with instancing to keep all modification symmetric)
|-- Wheel 1 (Object)
|-- Wheel 2 (Object)
However the RightWheels group has a negative scale z = -1.0 and causing a normal problem after export .fbx files to Substance Painter. When I try to solve this by freezing transform, it keeps the negatigve scale. I can manually change the scale to z = 1.0 but it breaks the symmetry, just like copy-and-translated objects instead of mirror effects.
Is there any options to keeping their mesh symmetric while completely disconnect their transform?
