Quick answer: Move the object origin to the desired pivot in your DCC tool (e.g. base of the feet) before export, or re-parent the mesh under a node placed at the correct pivot in-engine.
A door that swings from its center, or a character that orbits the scene origin when rotated, almost always has its pivot in the wrong place. Engines transform around the mesh origin, so if that point was never set deliberately it inherits whatever the modeling app left behind.
How to fix it
1. Set the origin in the DCC tool
In Blender, move the 3D cursor to the desired pivot and use Object > Set Origin > Origin to 3D Cursor. Place it at the base of a prop or the hinge of a door so it rotates correctly after import.
2. Snap to world zero for placement-friendly assets
For modular pieces, set the origin to a clean grid point so the asset snaps predictably. Confirm the origin sits where you expect before exporting the FBX or glTF.
3. Wrap the mesh in the engine if you cannot re-export
Parent the imported mesh under an empty/Node3D placed at the intended pivot, then rotate the parent. The offset child mesh now turns around the correct point.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
A crash you can name from its stack trace is a crash you can usually fix in minutes.
