Remove(context, self.thisObj, self.Prop)
location: <unknown location>:-1
Cause: Python script execution error when this happens.
There are many cases of errors occurring. It happens naturally.
Case 1: Code (wrong code, typo).
Case 2: Add-on (add-on enabled, not compatible with current Blender version, cannot run, conflict, etc.).
Case 3: Human error (some kind of operational error).
Case 4: Importing and exporting 3D objects (3D models) (formats: FBX, PMX, VRM, etc.)
etc…
Case 1: Code
Solution 1: Modify the code.
Solution 2: Correct the typo.
Solution 3: Make it an absolute path.
Case 2: addon
Match the add-on version to match the Blender version.
Case 3: Human error
Since that operation (obviously) cannot be performed, give up and think of another method.
ケース4
Solution 1: Modify the 3D object.
Solution 2: Set the import or export settings to default and check the changes little by little.
Solution 3: If you use the add-on: Better Fbx Importer, Exporter (paid), you won’t have many problems.
Solution 4: Check if the add-on is enabled and the version is correct.
Solution 5: Use volunteer add-ons. (unverified)
Search for “blender fbx exporter github” etc.
