Do you want the Glow to move relative to the object, pulse or have noise?

[Gon Perdigao]

i want that the glow follow the object, and also to have a pulse.

Later on, i try turning on and off the glow, and giving keyframes, but the pulse is not natural.

Is there a way to make it like a light turning on, that it flashes some times and then is on all the time?

Thanks a lot

Have you tried using the random and frequency parameters in the glow channel?

[Gon Perdigao]

yes, but the result is so smooth, that is not what i wanted (even using high values), the best result till now is turning on and off the glow, but i’d like to do it as i use to do in after efects, using a wiggle expression, is there a way?

You should reduce — not increase — the period setting to get a more chaotic look.

If you want to go another route you could create an expresso and use a noise node to drive the glob parameters through a range mapper — but that’s essentially the same thing as using the settings in the glow channel (except it gives you the ability to affect size as well as brightness).
