Defining a Master Light Material

At times it is best to have a master material and set local overrides per light. This can be done within the GafferThree node by creating a master material and assigning it to a light. Any changes made within the light’s Material sub-tab act as an override for the master material.

Creating a Master Material

In the GafferThree node’s Parameters tab , right-click in the Gaffer object table, and select Add > Master Material or press Alt+M.

A master material location is created inside the GafferThree node.

Assigning a Master Material to a Light

1.   In the Parameters tab, double-click below the Shader heading in-line with the light you want to assign the master material to.
2.   Select the master material from the list (master materials are displayed in pink).

The master material is assigned to the light.
