Not really a bug, more like a quirk, you can see the "pseudo" in the pseudorandom number generation routine for the loop Randomizers in the following filter. Any Variation setting (by slider) up to 62 will be not very random. Above it, randomity reigns again.

Good find. I thought patterning in Randomizer was fixed. We did test it for patterning, but apparently we overlooked something pretty big. Thanks.

That's a bug point for ThreeDee.

Possibly still the same issue: This filter attempts to generate a random color, but every time the first random value (used for R channel) is almost zero, so we get only greens and blues, no reds, yellows or violets.

(or then it is a LUA math.random issue)

We have looked into the math.random issue. better late than never, right?
In LUA 5.1, when you call math.random for the first time, it returns nothing indeed. It was fixed in LUA 5.2 (the version that is currently used in FF) but we have to inherit the old behavior for the sake of compatibility with all existing script filters. The workaround is pretty simple: you need to call math.random several times and do nothing with the first call. All subsequent calls should work correctly. Please consider it a FF-specific quirk, not a bug. |

Ok, thanks for the clarification. Possibly a good thing to include in the Scripting wiki?
