Chaosgroup V-Ray is required to use this tool and it’s best to use with V-Ray GPU in ActiveShade (interactive) mode.

Light assistant was developed for in-house use at Dabarti and released for free to general public. We’re using only V-Ray in our pipeline so at this stage there are no plans to fully support any other renderers.
