MT_FractalBlocks is available in Reactor, which mimics much of the function of AE's Blocky style Fractal Noise. The MT_Voronoi Fuse is… well, it needs some work. I'm probably about six hours away from having a satisfactory static Worley (sometimes known as Cellular) field, 8 - 12 hours from reasonable animation of both the Voronoi and Worley (they're the same algorithm, just different rendering methods) fields. The trouble is finding those hours, particularly since the Version Control script is a little higher priority.
If you have CustomShader3D, there's been some work on bringing ShaderToy code into Fusion. Keep an eye out at Steakunderwater for more of that in the near future, I think.
https://indicated.com/blackmagic-fusion ... shader-3d/Other projects for the intermediate future include the Diamond-Square algorithm and Wood/Marble, both of which are fairly simple. I'd also like to implement some variants on the Game of Life. I'm not sure if that would be useful as a noise generator or not, but it would at least be an interesting exercise.
Of course, if any other Fuse writer wants to tackle any of those first, I'd be quite happy about it!
