I wanted to load a 200MB g3dj file, but it couldn't be loaded for a long time, and then the memory overflowed. Can anyone tell me what to do when loading a large 3D file? thanks

You could try G3DB instead - this will be faster and smaller since it doesn't have to parse JSON. But it sounds to me like your model is far too complex for a mobile game. Keep it relatively low-poly for good performance and app size. E.g. the player model in my ghost game is 140KB as G3DJ.
