ABSTRACT

V-Ray IES is exactly like a spotlight, with a photometric curve.

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)

DOWNLOADS

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.
