I added loaded a glb file of 700 mega bytes into Godot 4 and it crashed it should I use another file format

  • No, I think you should consider if you could separate the model into segments you could export as separate objects/files. I presume the file is so big because it's a whole level/scene or such in which case there should be ample opportunity to split it up.

How the hell did you manage to make a 700mb glb file?

    Don't do that. Make glb files only when you're sober.

    You likely want to export just one patch of grass (or like 5 or 6 variations) and then use MultiMeshInstance in Godot for better performance.
