Transform: Tilt values in curves are not transformed
Confirmed, LowPublicTO DO

Description

Blender Version
2.8, 2.81

Short description of error
When mirroring curves, tilt values are not mirrored.

In edit mode, MIRROR(or SCALE -1) dose not change tilt values.
So I can not get mirrored result (bebel geometry).

(In object mode, I can get mirrored 2 curves by MIRROR(or SCALE -1),
But JOIN the two curves results not mirrored tilt effect.)

Exact steps for others to reproduce the error
Open:

  • The file contains 2 splines. One is a scaled duplicate of the other.
  • Note that the tilt of the corresponding point remains the same on both splines.

Unsure if I understand correctly:

  • is this about the mirrir modifier?
  • is this about mirroring in objectmode?
  • is this about mirroring in editmode?


Above file has a path mirrored in objectmode and negated tilt (by hand). Dont think this would be expected default behavior?
Possibly I am misunderstanding, but in order to proceed here, we would need an example .blend file with exact steps to reproduce (and an explanation of what the expected [vs. the actual] behavior would be...)

Although it would be interesting to support, this is not a bug.
But I'll put it as To Do to be revisited another day.
