The models are broken up into N sub-(sub-)models, one for each texture, but all faces using the same texture are drawn as an instance, making for both reduced draw calls and reduced index buffer use (and thus, hopefully, reduced bandwidth). While texture animations are broken, this does mark a significant milestone towards implementing shadows as it should now be possible to use multiple threads (with multiple index and entid buffers) to render the depth buffers for all the lights.
