Will LightRigger need to be installed on render nodes for network rendering?
Never. The entire LightRigger system is composed of 100% standard 3ds max lights, objects, groups, controllers and linkages. There are no scripted or SDK plugin classes used at all, so a render node only sees a scene with standard 3ds max components. LightRigger scenes can be used on workstations and render nodes that do not have LightRigger installed.
