Voronoi noise for Octave Noise node #35
Description
A voronoi noise option was added to the simple noise node in #31 , but due to how it was implemented, offsets are weird and don't work the same as Perlin. There's no performant way to directly sample a Voronoi point without generating the whole grid, so to make it work for the Octave Noise node, a whole new code path would have to pre-make noise maps and sample them when building the layers. For now, you can manually layer Voronoi noise using the simple method and node chains if this is needed.
