Volume rendering
Probably the most beautiful new feature is rendering of volume grids. These can either be provided directly by a plugin/script or via OpenVDB files. Creating a VDB file is typically done in a package such as Houdini or with a third party plugin available to many other packages such as TurbulenceFD. Once created, it can be loaded into Octane for rendering.
Getting Started
- Right click in the node graph, select "geometry" then "volume".
- Select a VDB file to import (sample).
- Create and connect a Volume Medium to the volume (right click node graph select "Medium" then "Volume medium").
- Click on the volume node to start rendering it or right click and select "render". You may need to zoom out to see the volume and you should have some non-black environment set up, since the default volume render setting is some absorption only.
