Preload all model textures to avoid stutters during gameplay
The texture atlases for loaded models should be prepared at an appropriate time, like when loading a map, instead of just-in-time when the models are first rendered.
Model Renderer: Initialize loaded 3D models during busy mode
To avoid stutters during gameplay, 3D models from all loaded packages
are initialized for rendering during busy mode. This includes copying
the model textures to one or more atlases.
