[b]Hello,
I have a design/ interior design project where inside glass tubes are some bulbs and I would like the light to go from on the off slowly (reproducing the beating of the heart) and progressively actually. I really don’t know how to produce this kind of effect or even if it is possible? Becausethere will be several tubes and all of them will have a different « pace » but still progressively.
Any help would be awesome.
Thank you very much

Hello,
You want to make an animation I suppose.
To obtain a pulsing light, you can use a Neon Shader and animate its lumen value.
I have made a test and I think it might be what you are looking for, unfortunately I cannot upload it to this post because it is an mp4.
Give me your email I will send it to you.
Hello, thank you very much, yes I think that’s the effect I am looking for 
I’m not sure how to send you my email privatly?
I’m new here, I don’t know how to send pm?
Thanks anyway,
Laura
