Flickering Flame Light
I've searched the forum and how to create a flickering light has been answered a few times, resulting in this expression that I'm currently using...
pointLightShape1.intensity = rand(0.5,1.5);
Unfortunately, generating a new value every frame looks unnatural (and is epilepsy inducing!). So, I'm after an expression which generates the new intensity value every random number of frames (between 5 and 15, say).
I've come across expressions which will change the value every set number of frames (e.g. every 5 or 10), but this looks unnatural. So is there a way to do this?
I'm fairly new to Maya and struggling to get my head around the MEL stuff!

I did try using the noise function at one point. The effect was very smooth, more like a dimmer switch reducing and raising the light, not really a 'flicker' a flame would produce.
Still, thanks for the suggestion, I'll have an experiment...
