Octane Volume


The Volume node imports 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/. data. You can create this node by choosing Octane VDB from the Octane menu. You can also create a node from Octane Nodes category in the Hypershade window. To set up a VDB-based volume, load a VDB file and add an OctaneRender® Volume medium to the Medium attribute.
