A ground smoke creeping on the floor in VDB format.
Contains only a density (39,891,053 voxels) field. You can also fill the vdb with particles and convert it to a mesh to get the polygon version of the smoke and make it an .fbx or .obj.
The preview renders are just examples which are simulated(Sparse Pyro) and rendered(Mantra) inside Houdini.
Keep in mind that this is not an animated .vdb sequence, it is a single .vdb file.
