Here is some custom Nuke noise, similar to those noise functions I posted as Shake Noise3d. I will call it Nuke Noise. Not to be mistaken with Nukes built in Turbulence or fBm pixel generation methods. We have Nukes noise function (noise (x,y,z)) being called via some User Knobs. Again there’s control over Frequency, Seed, [...]

Bill Spitzak from Digtial Domain wrote these pages on converting floating point images to 8-bit. Very interesting read even though it is a bit outdated. From memory this guy wrote quite a bit of the Nuke code now taken over by the Foundry.

Here we have the noise3d function being called via some local variables. I find it really useful for some many different things. A must have …
And here’s the shake code, just copy and paste into shake:
Noise3d = Fade(0, (1*(noise3d((time+(timeOffset*100))*Frequency, (seed*5), 0)*2-1)*Amplitude+(Amplitude*.7))+amount,
float Frequency = 0.4351687,
float seed = 0, float Amplitude = 0.408525735,
float timeOffset = 0, float [...]

Once I get a decent collection together I’ll post them with tutorials. Meanwhile here’s a crazy looking one I’ve combined in Photoshop by shooting straight at an [...]
