Light Assistant helps with aligning reflections and adjusting the parameters of V-Ray lights.

Main features:

  1. Interactively ALIGN lights reflection directly on the geometry. Hold shift for “Rim Light Mode”.
  2. Interactively change light distance, size and rotation in ADJUST mode.
  3. Quickly control V-Ray Light properties with “Light Lister” like interface.
  4. Adjust light intensity using Exposure Value (EV).
  5. Align and Adjust modes work well with some non V-Ray lights.
  6. 10 Softbox presets in material library included.
  7. Designed to work perfectly with V-Ray GPU (RT)
  8. Chaosgroup V-Ray is required to fully utilize this tool and it’s best to use with V-Ray GPU in ActiveShade (interactive) mode. However it may work with different lights if Align Selected or Adjust Selected is used.

    Light assistant is tool developed for inhouse 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 support any other renderer.
