I'm rendering animations that have looping points to save on frames and add flexibility.

Whilst every animated element is set to loop every 50 frames I can't see any way to loop the noise?

I'd like to have to have some nice movement in the visible light cones if possible!

I need a solution for the standard renderer I'm afraid.

Thanks!

I don't think so

- On the spot light > noise quick tab - turn that noise off
- create a new material and turn on only the luminance and alpha channels
- in the luminance channel add a solid color or static texture if you want
- in the alpha channel set the texture to noise and adjust the noise as you like.
- in the noise you can set the animation speed AND the "loop period" parameter is key. I believe it is in seconds, not frames so you need to do that math based on the FPS set in the project settings.
- assign that material directly to the spot light.

Let me know if that's what you're looking for.
