Extremely Large GC Allocations

[BananaHemic]

I compiled this plugin from commit 16f3112 in Release mode. When loading the VC.glb model via LoadSceneAsync() in a coroutine, the process freezes the editor for about 16 seconds, and generates 2.8 GB of GC allocations. This is substantially more GC allocations that I would anticipate given the size of the model.

3D Viewer loads the model in a few seconds, and Task Manager shows a memory usage of around 120MB.

Is this expected behavior, and can anything be done to improve the performance?
