Maya Plugins

OpenVDB

The OpenVDB plugin for Maya is supported by RfM. Users can find a button on the RenderMan shelf for creating an OpenVDB visualizer node. A PxrVolume with a PxrPrimvar for density gets wired in as the shading group. Click on the shelf button, browse to a file like bunny_cloud.vdb. Click render. Behold your bunny cloud.

RfM emits either RiBlobby or RiVolume, depending on whether the "surface" checkbox on the node is enabled. Additionally, if the openvdb file only contains level set data, we render as a RiBlobby. In this case the user will want to wire in a different shader than the default PxrVolume. RfM's custom shading group attribute can be added to wire in a shading group.

Built-in AOVs and Light Path Expressions

RMS fully supports RIS mode's built-in Arbitrary Output Variables and Light Path Expressions.
