Hi!

I used my [InstancedMesh2](https://discourse.threejs.org/t/three-ez-instancedmesh2-enhanced-instancedmesh-with-frustum-culling-fast-raycasting-bvh-sorting-visibility-management-lod-skinning-and-more/69344) library to create a simple smoke effect.  
It was easy using the API to set opacity/add/remove instances 🚀

I hope the code is clear and easy to read ❤
