Grasshopper Rig Components
Starting with V-Ray6.10.10, the migration of Rig components, created with V-Ray 6.10.00, requires parameter rewiring.

Grasshopper

Loading Rig components from projects created with V-Ray 6.10.00 into newer versions, requires parameter rewiring. In V-Ray V-Ray6.10.01 some input and output parameters of the Grasshopper Rig Light components have been rearranged. Due to this reason, when a project created with the previous version is opened, the parameters appear to not be wired properly. In such cases, rewire the parameters manually for proper project performance.
