The SoPathTracerTagVolume module provides an 8bit tag volume, that can be used by a SoPathTracerVolume and SoPathTracerVolumeInstance to tag objects in the volume.

Each tagged object can be rendered with its own LUT (via a 2D LUT on the LUT inputs of the volumes) and it can each have its own SoPathTracerMaterial (via the inMaterial scene of the volumes).

A tag volume has a Volume Name. This name can be used in multiple SoPathTracerVolume and SoPathTracerVolumeInstance modules by specifying the volumeName as tagVolume.


In this rendering, the bones are tagged using a tag volume to allow different materials and LUTs for bones and vessels.
