- A Roblox Developer Forum report says a weapon rig fails to import into Blender with a "missing bone" error (snapshot checked on 2026-04-03).
- Reported setup: cautioned's Blender-Roblox animation plugin v2.4.1 on Blender side, plus the latest Roblox-side plugin as of 2026-04-03.
- The creator already tried re-doing Motor6D links ("re-motor6d"), but the import problem stayed.
- [2026-04-03] New community bug report flagged: weapon-included rig import throws a missing bone error.
- [2026-04-03] Reporter clarified that "gears" and "vfx" folders are just organization folders, not special rig logic.

Developer Context
This is a creator-tool workflow issue on the Roblox platform, not a live gameplay patch.
Inference from the report: the importer is likely doing strict bone validation, and one expected bone is not found when the weapon rig is included.
Why that matters: strict checks can prevent bad animation data, but they also block import if names or links are off by even a little.
Helpful test plan for creators:
- Import a no-weapon version of the rig first.
- Add weapon bones back one step at a time.
- Match bone names and Motor6D names exactly between Roblox Studio and Blender.
Why You Should Care
- If you build shooter or melee games, this can break reload, equip, and recoil animations.
- Finding this early saves a lot of hours before you ship your next update.
- A clean import pipeline means fewer "why is this frozen?" moments for your team and faster content drops.
- Q: Is this a bug in Roblox gameplay?
A: No. It is a creator pipeline issue between Roblox Studio and Blender. - Q: Which versions were reported?
A: Blender-side plugin v2.4.1 and latest Roblox-side plugin, as reported on 2026-04-03. - Q: Do "gears" and "vfx" folders cause the error?
A: The reporter said those folders are only for organization, so they are not the main problem by themselves. - Q: What is the fastest first fix to try?
A: Import the rig without the weapon first, then re-add weapon bones one by one and verify exact name matches.
- Q: Is there an official confirmed fix in that thread?
A: Not yet, as of 2026-04-03.
