VRay Light Select RE

[NicoC]

Hello

Are there know limitations of VRay Light Select RE ?
I'm trying to really use it for a project, and I get several of these RE totally empty, whereas others are ok ... for example, are lights using Exclude/Include feature supported ? are there light options that have to be ON to get expected result in Light Select RE ?

Thanks in advance,

Regards.

I use them frequently and didn't have any issues so far. Be aware though that the LightSelect RE includes both diffuse and specular component.

Edit: AFAIK they also only work with VRaymaterials. I guess you already checked the black REs for eventual turned off lights or visibility. Wo maybe you got a wrong material applied?

Another known limitation is that the Global Illumination component cannot be extracted per light in Production and VrayRT renderer - it is only supported in RT GPU so far.
It would be a good idea to send us some example scene for investigation if you have any issues with Light Select RE.
