Currently going over 65k vertices on a single chunk causes a soft crash, which is very likely on tile sizes larger than 16x16x16. This is due to a Unity limitation of 65,535 vertices per Mesh instance. There are a few optimizations that can be made to alleviate this (such as merging adjacent faces) but Chunks should support generating a list of Meshes. This will also require generating a set of MeshFilters, MeshRenderers, and MeshColliders.
