Lesson 7 | V-Ray IES – Demo

Updated to V-Ray 3.5
V-Ray IES is a spotlight, with a photometric curve:

// VIDEO IN ENGLISH //

// VIDEO IN ITALIANO //

// VIDEO EN ESPAÑOL //

CONCEPTS:

  • Click “NONE” to assign a photometric curve (.ies file)
  • You can download tons of .ies files for free on lamp website producers
  • “Nice.ies” is a famous IES file that works really good
  • Power is not expressed in “watts”, so don’t worry about so high values
  • The V-Ray IES power is measured in candles and lumens (we use lumens, but nothing changes)

 EXERCISE:

Download this file and repeat the same procedure you watched in the video.

Note:
V-Ray Ies just simulate the light. Use VRayLightMtl to simulate the light source.
Use “compensate exposure” for the fast setting – If your V-Ray does not include this option, just increase the multiplier.
