Hey guys, wanted to drop a line about a useful technique for achieving fluid like warping effects with vector warp. I have a write up here:

Hey everyone, i created a quick tutorial for creating fBM noise with the FX-Map node. It assumes you have basic knowledge with designer and most of nodes.

The 3d Noise nodes are great, however it would be awesome if we could use them to generate tiling 3d noise lookup tables, similar to what Ryan Brucks does for UE4: http://shaderbits.com/blog/authoring-pseudo-volume-textures. These would be invaluable for advanced shading techniques.

Also, any chance we could get some 3d vector noise nodes in the future?

This is essentially a color palette analyser.

I'd attempt to make this node by hand, but it requires iterating over every pixel and storing the values in a table. You then have to sort the table by number of entries in each value and return the top X number of results. This is pretty much impossible to do in the pixel processor, so i'm hoping that you guys can make this an atomic node or a function.

The image it would return would be similar to quantize, but it would instead fill in surrounding similar colors with a common average.

There's a program called ToonIt! that has a bunch of filters that do similar things, but it's only for photoshop, and... well... who wants to use photoshop anymore?

Hey everyone,

I noticed the new Blue Noise node and i'm wondering if anyone has any idea what the common applications are for it. Couldn't find much on Google about it's uses.
