This defines the time that will run before Skatter asks you if you want to abort the current calculation.
This parameter limits the number of displayed items in the preview, for performance issues. This means that if there are more scattered items than this value, they will not be displayed in the preview, but will actually be generated.
It defaults to 50'000.
Every "random" parameter is not truly random, but depends on a "seed". This way, you get consistent results when regenerating, or when reopening Sketchup. You always get the same results when keeping the same parameters and values. But if for some reason, you want a different result than what you see on screen, simply change de "Random seed" value, or click on "New seed".
