Adding a custom animation track to imported mesh.

Question

I'm in the process of testing out attack animations for my enemies and wanted to add a custom track to call a function to activate a hit-box. The custom track is lost every time the mesh is re-imported though. I couldn't find a lot of documentation on what to do and I feel like I'm missing something. Here's what I did:

1. I made a simple 3D model with some crude animations and exported as .glb.
2. On the import tab, under "Animations", I selected "Storage->Files" and turned "Keep Custom Tracks" to "on".
3. I tried adding a custom track in the .glb file's inherited scene and I also tried adding a custom track in the scene that makes use of the inherited scene, but the custom track was lost both times.

Let me know if I'm doing something wrong.

Comments

I can't get custom tracks to save at all on 3.3.3, even new instanced scenes with the adjusted import settings display the warning icon about making changes to imported animation.
