You could, but doing meshes like that wouldn’t really have a whole lot of breakaway/interaction. I was going for an organic, archaic cloud field, and didn’t really see a lot of opportunity to morph individual pieces into larger formations in a natural looking way. Also it wouldn’t really help to fly around within a big empty cloud mesh, as the space on the inside of a mesh is still hollow. You could fill it with slice cards at a bunch of angles for a static piece, but then there’s the issue of massive transparency overdraw that would cause.
Cheers!
