Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system:MacOS Monterey 12.3.1
Graphics card: M1 Max
Blender Version
Broken: 3.4.1
Worked: 3.3
Short description of error
Deleting a hierarchy crashes blender when there is more than one level of hierarchy.
Exact steps for others to reproduce the error
Make three cubes.
Blender instantly crashes every time
Workaround: It works to "Select Hierarchy" then choose "Delete". The crash only happens when choosing "Delete Hierarchy"
Here is a testing .blend file with some relatively more complex relationships:
This is still broken in the current next release candidate: blender-3.5.0-candidate+v35.6e51f8d2023a-darwin.arm64-release.dmg
Hi, thanks for the report. I'm not able to redo the crash locally.
Can you share .blend file where this happens. Or can you try out the file I've attached?
(I'm selecting Cube2 and calling the "Delete Hierarchy" operation)
HA that's so weird. Yours deletes fine and I don't see what the difference is. I've attached one that crashes for me.
Wait...can you try it again, but when you parent both times, use "Keep Transform"
Can confirm. But crash does not happen on every attempt. I'll check.
From further testing, this appear as a regression.
Will bisect...Still hit and miss, crash happens sometimes and sometimes not.
Checking for possible solution...
