I have a scene that uses a few different lighting presets (sort of like a theatre stage). If I don’t want unlit lights eating cpu/gpu cycles, is it enough to set dimmer to 0, or should I uncook lights or unlist them in render TOP?
I’d look at all the parameter pages. I’ve done this before but don’t remember what the specific parameter name is
Ya, I’m familiar with the pars of a Light COMP, I’m asking about the most ‘correct’ way to turn lights off such that they aren’t adding to render time when they’re ‘off’. Is the dimmer par set to 0 enough? Say there are 100 lights in my render, but I only want five of them on at a time. What should I do with the other 95?
You could use replicators, but I wouldn’t cook/uncook, I’ve seen pretty intense stuttering with doing that. Just making it active or dimming it is probably your best bet, but others may have better input.
This is in the wiki for the Light COMP, Dimmer parameter: Dimmer dimmer - This parameter changes the intensity of the light without affecting its hue. Lights with Dimmer intensity below 0.001 are ignored. This optimization allows lights that are set to 0.0 to not be calculated in the scene.

Brilliant, thank you Greg. Apologies for not seeing it myself in the documentation.
For anyone interested, it is at this anchor link: TouchDesigner Documentation
Added it to summary as it’s a common question.

Conflicting in summary, where it says ‘.001 or less’ and below it says ‘less than .001’. Typo?
