System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 560.94

Blender Version
Broken: version: 4.2.0, branch: blender-v4.2-release, commit date: 2024-07-16 06:20, hash: a51f293548ad
Worked: (newest version of Blender that worked as expected)

Short description of error
The position and rotation of the null parented on any 3vertex object do not correctly calculate the transform matrix.

Exact steps for others to reproduce the error
Create sphere > edit mode > select 3 vertices > shift+s > cursor to selected > add null > select first null then object > ctrl+p > vertex (triangle)

  • in blender LTS 3.6 the null stays and move by the triangle of the sphere (correct)
  • in 4.2 the null goes away from triangle and object

Hi, thanks for the report. Can confirm in 4.2.2. However, this appears to be fixed already in 4.3, I will check.

In main/4.3, 29edcef5c9 resolved the issue.
@JacquesLucke hi, can we backport your fix to 4.2?

Yes, the same fix should work in 4.2 I think.
