Constraint-ed child object behave incorrectly when apply transform on parent
Closed, InvalidPublic

Description

System Information
Windows 10 and NVIDIA K5100M

Blender Version

Worked: none

Short description of error

when applying transform to any object who have child object with constraint, the child object will produce irregular transform.

Exact steps for others to reproduce the error

  1. create 3 objects A,B,C.
  2. set B as A's parent.
  3. make a "Copy Rotation" constraint in A, target set to C. (Preferably C would have a non-zero initial rotation value before this step)
  4. select B and hit Ctrl-A, select "Scale"
  5. then you can see the wired behavior in A.

any ideas? would it be related to depsGraph or something? or any plans to correct the behavior in future infrastructure design? Thanks for looking in to it!

edit: Also tried --enable-new-depsgraph ,didn't work either.
