Nice Noise for Spark AR
A downloadable tool
This will handle scrolling noise for you. I use scrolling noise as a basis for many effects and found myself re-creating this setup many times - so here it is in a single handy node.
I included a sample scene so you can see how it works. There are actually 2 patches - one for Screen UVs (if making a post effect) and one for regular UVs (for your 3d models).
You just need to supply a noise texture and it will handle the scrolling and distortion easily. I added 2 in the sample scene... if using your own, just remember to set it to set it's U & V tiling mode to repeat.
Loop Length is essentially scroll speed. Mix Value handles self-distortion, and usually this looks good between 0.2 - 0.5, but feel free to play around with it.
