This page provides information about Light Mix Render Element in V-Ray for Revit.
The V-Ray Light Mix Render Element provides adjustment control to the lights in the project from inside the New V-Ray Frame Buffer.
When the V-Ray Light Mix Render Element is added prior to rendering, the intensity and color of lights and of light-emitting materials can be changed directly from the VFB during and after rendering. Lights can be enabled and disabled while rendering without the need to re-render the final output or to navigate to individual lights parameters during Interactive Rendering.

The example below shows two different light setups created with the help of Light Mix: daylight and dusk. The Daylight appearance is achieved by using sunlight and an additional softlight to simulate light coming from the outside. The Dusk appearance is achieved by setting the sun Multiplier to 0, changing the color multiplier of the outside light to blue, increasing the intensity multiplier of all interior lights and tinting them with warmer colors (all ceiling and built-in furniture V-Ray Lights), adjusting the self-illumination multiplier of desk and ceiling lights shaded with Emission.
