And voila:
Real-time wind occlusion! Notice the small gap at the bottom of the walls, it actually lets a draft through if you look carefully at the rope and cloth. So you should be able to create pretty intricate setups with that level of precision.
And you are correct about having this use an “LOD” type setup, but I think I’ll leave that up to the developer since toggling it simply involves setting a bool. I will however add a coarser grain, high perf, alternative which will only use the bounds for checking wind occlusion of the entire object.
