Archive notice: This article covers LightMix in the V-Ray 5 beta from May 2020. Current controls and compatibility may differ.
Chaos introduced LightMix and layer compositing in the V-Ray 5 frame buffer.
Post-render relighting
LightMix allowed artists to adjust the colour and intensity of scene lights after a render completed. The workflow moved lighting iterations into the VFB, reducing the need to launch a full rerender for every balance change.
VFB compositing
The same beta revised the frame-buffer interface and added layered compositing. Lighting adjustments and image operations could therefore be evaluated together inside V-Ray.
Lighting teams should test render-element setup, saved LightMix presets, colour management and final-output parity before using the beta workflow on production scenes.
