I think the problem is to call `createVertexBuffer` at each frame (maybe several times). It would be better to create the vertex buffer once and update it (with `ThinEngine.updateArrayBuffer`, which uses `bufferSubData`), but I don’t know if this is possible, I don’t know this voxel engine.

On the other hand, do you know [Divine Voxel Engine - Voxel Engine Made With Babylon.js - Alpha 1.0 Out Now](https://forum.babylonjs.com/t/divine-voxel-engine-voxel-engine-made-with-babylon-js-alpha-1-0-out-now/30591) ? Maybe it could be an alternative choice.
