The Standard Volume Medium node is a volume medium node with comprehensive controls for adjusting volume, scatter, transparency, emission, and temperature parameters based on imported VBD grid data. Unlike the Volume Medium node, this is designed for fire/flame shading.
In order to use the Standard Volume Medium node, an Octane VDB must be added to the scene first. This is documented in the Using Volumetrics with Octane Render for LightWave page.
warning
PLease note that it is not currently possible to use the Gradient or Gradient 2 nodes with the Standard Volume Nodes
