Looping noise on a light’s ‘visible light’. Possible?
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.

Hello, Sam, I know I’m about 1 year too late to this party… but it seems there’s no way to get the texture method to affect the visible light, it only affects the luminance itself, i.e. the results of the noise texture are only seen on the surface receiving the light; the light source itself continues indivisible, and if you activate its visibility, the light “cone” or “halo” (because you can also pop a texture on a point light) remains solid, rather it shows no noise, which is the wanted effect.
Stuart, I’m wondering if you were ever able to find a way to loop the noise on a visible light?

In the Attributes Manager, on the General tab of the Spotlight, set the “Visible Light” attribute to “Volumetric”.
