How to Assign Emissive Material on Objects in Maya with ProRender

Emissive Materials can turn any object into a light source that can be used to illuminate a scene. You can use the RPR UberMaterial shader or RPR materials of the emissive type to add emissive properties to faces.

How to Create and Assign Emissive Material on Selected Objects

You can assign emissive materials to objects in either of the following ways.

1. Select the target object from the menu bar, and select Radeon ProRender > Lights > Create and Assign Emissive Material on Selected Object. An EPR-enabled RPR material is created and assigned to the selected object.

Or, switch to the Radeon ProRender shelf and click the Create and Assign Emissive Material on Selected Object An EPR-enabled RPR material will be created and assigned to the selected object as above.

2. Assign the RPR Uber Material to the object and adjust the parameters on the Emissive tab in the Attribute Editor.
