A violent tornado VDB model that is separated into three parts which are Top, Main and Bottom. So in the zip you'll get three different VDBs. There is only density information in the VDBs. You have control over the three parts (you can see them different colored in preview images) and can change their density, position, scale or shaders individually. (Top = 14,314,174 density voxels, Main = 27,046,071 density voxels, Bottom = 14,098,886 density voxels)
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 with different lighting setups.
*IMPORTANT *= This is not an animated .vdb sequence, it is a single .vdb file. There is no animation, this is just one frame.
