OpenVDB

To load a VDBDreamworks’ open-source C++ library housing the data structures and tools implementation for storing and manipulating volume data, like smoke and other amorphous materials. The purpose of OpenVDB is mostly to have an efficient way to store volumetric data in memory and on disk. It has evolved into a more general toolkit that also lets you accomplish other things, such as fracturing volumes, converting meshes to volumes and vice versa. However, it does not include a computational fluid dynamics solver, and therefore it cannot procedurally generate smoke or fire. OpenVDB is fully integrated as a library in OctaneRender. For more information about OpenVDB, please see http://www.openvdb.org/. file, add a Carrara Volume (Fire or Fog) to your scene. Select the volume and open the Effects Tab.

You can scale and move the VDB volume by manipulating the dimensions and position of the Carrara volume.

You can set the import settings for the OpenVDB file by pressing the Import Settings button.

You can assign an Octane Medium shader to the volume node.

You can animate a volume by creating a list of OpenVDB files. You can then create key-frames on the Image Index slider to control which file to load on a given frame.
