I am currently working on a laser effect, and am looking for a way to “randomize” the emission value of the laser, similar to the wiggle expression in after effects. The current node setup I have is very simple, just a ColorRamp from my darkest to brightest value connected to the strength of the emission. I have tried a few methods to get a random 0 to 1 value for the factor of the ColorRamp but have ran into an issue. The issue is that with purely random values, the strength will skip around from the darkest to brightest within a frame or two. Rather than pure random values, I would like the value to essentially slide around “randomly” between 0 and 1. This way there will be more gradual dips and spikes in the brightness of the laser, but will also not just be pulsing on a linear path from 0 to 1 and back to 0 again. Is there any way to make this happen procedurally or with minimal keyframing?
Thanks so much, all thoughts would be appreciated,
