I am looking for a really simple way to cause the value in my RS_Incandescent shader to randomize in quick intervals, simulating the flickering pattern of a neon bulb. I was looking at some noise functions, but I don't see a way to control them to make them do what I want. Also I'm still kinda green in VEX.

Any ideas are appreciated!

I am trying to cache a water simulation in the console, because the scene also contains a skinned character that is pretty complex, and requires considerable cooking time, so to save UI overhead i thought of creating an output node that plugs into the dop path for the water sim, which is a simple 300x300 flat tank, and use the render command to run the node in console.

If i cache the water sim from Houdini UI, the cached files are less than 50MB each, but if i try to launch the render command from the console to my dop path, the cached files generated are 450MB each. Any idea what i might be doing wrong?

So in the end i was able to simply keyframe a ramp in the RS material blender blend color channel to more or less match the trajectory of the tracks, which feels a little convoluted, and probably not very practical for more complex projects. Any way to simplify this workflow so i don't have to do a lot of things separately?
