Light and Sparkle

Hello all,

I continue to search and try to use V-Ray for Revit in production.
This time I’m looking for a way to render the source of the light. In the picture, you can see a lot of dot : these are light.
I want to render their light and source.
I’ve try to use an emissive material (day picture) and even try to put little light (100W) in the second picture.

I’ve seen it in this Webinar : https://youtu.be/8034M4jd4JE?t=3m54s
Never found how it was done

Thanks,
Mickaël

(sorry for my english)


Think I"ve found a start of answer in Camera Effect.
Now : make it works :stuck_out_tongue:
