implicit - Arnold for Katana

The implicit scenegraph location is treated identically to the volume location, with a few restrictions:

• geometry.type: Only string values volumedso and volumeplugin are allowed
• The Arnold node emitted is of type implicit instead of volume (KtoA 1.1 / Arnold 4.2), or the custom Arnold node specified by rendererProcedural.node (KtoA 2.0 / Arnold 5.0).

All other translation, including procedural arguments and arbitrary user data, follows the same rules.  For more information, please see the volume location.
