Hello guys, is there any good way to loop a fractal noise offset without going into fade in/out technique?

Hopefully I'm understanding your issue correctly! Apologies otherwise.

You could add a time expression to the Evolution: e.g. "time*100" (but dont use the inverted commas!) the higher the number in the expression, the faster the evolution speed.

hope this helps

It's not the evolution i want to loop, it's the offset, i want to make it move vertically/horizontally, but can't seem to find a good solution other than precomposing and crossfading.

I've figured that tiling the fractal noise and adding the offset afterwards is working just fine, but i wish it had a native offset loop within the setings.

fractal noise has a loop option, it only works for evolutions but it's very useful.

i hin you are animating the offset... there's isn't a way to loop that seamlessly that i know of.... however, i've had more success using gradient wipe other than a simple crossfade.

you might also be able to use linear wipe if you can time the wipe completion rate with the movement of the noise offset, and feather it bit.

There's no good way I know about. You'd have to loop all the animating parameters. You can do it, but it could be a real pain.
