I present a sequence VDB smoke model. It lasts for 20s. The video is rendered with Octane Render. You have to import the VDB file in your 3D software and set the density, size of the volume step, etc. It is very fast. It only has density field. The size of the voxel is 0,05. They works very fine and looks very realistic. They have not polygons or textures or materials. They are voxels 3D. You can pass through them.
How to use it: download in the same folder all ZIP, z01, z02, etc and Unzip ONLY the *.ZIP.
I hope you like them.
