I can write Python code to loop over the lights and tell if they're on or off. I can set them on or off. And I've just failed miserably at finding how to get and set the intensity. Sure looks like "Intensity" is the magic word, but I'm missing something.

For an individual light, I can access light.LightType, LightOn, SetLightOn, SetLightOff, but, sigh, I cannot find how to get/set intensity.

Has to be simple but I can't figure it out.

So -- what's the secret, eh?

Nevermind. Naturally, after "giving up" and asking, I found it.

You grab the parameter from the actor and then you can use Value() or SetValue() to read and write it.

Thanks!

And also thank you for your footnote about reply notifications. Useful to know.

Its simple:
