Cloned lights in random colours

[simonEPZ3S]

Hi All,

Is it possible to have random colours (or a specific colour range) applied to a spot light that is inside a cloner?

I can do this with objects but cant see a way to do it with lights so not sure if it is possible.

Any help or ideas appreciated as I am trying to colour about 100 lights so I want to avoid doing them individually.

Thanks

Still hoping someone can provide an answer to the above question. Thanks.

So far, the only way I found was to use an operator

Thanks for the tip Stephen.

I have not used operators before but managed to get it working after taking a look at your setup.

What are you using the "Root" node for? I can get things working with just the first node.

Is there a way that you know of to have the randomized colors sit within a range? I would like to randomize throughout a pre chosen range of colors so I can avoid certain colors that I dont want appearing.

Thanks

This is exactly what I'm looking for! Just curious to know if it's possible to control the light strength with fields or a shader instead perhaps?

Thanks alot!

Not sure about fields, but you can change the exposure (using operators) as shown here.

Thank you very much @lee_griggs @!

Operators are new to me but are clearly extremely useful. Is there any resource available for the expressions used? If I can apply some noise or sine to my cloned lights I think it will do the trick, but I haven't been able to find an overview of what functions are available.
