It is perfectly possible to put a for-loop inside a non-for-loop or vice-versa. Again, you just have to be careful (with experience it gets easier).
For example, suppose that we want to create 50 spheres which are randomly placed inside the unit sphere.
So the distinction is clear: First we need a loop to create 50 spheres (a for-loop type suffices) and then we need another loop inside it to calculate the location of the sphere. It will look like this:
#declare S = seed(0); #declare Index = 1; #while(Index <= 50) #declare Point = <2*rand(S)-1, 2*rand(S)-1, 2*rand(S)-1>; #while(vlength(Point) > 1) #declare Point = <2*rand(S)-1, 2*rand(S)-1, 2*rand(S)-1>; #end sphere { Point, .1 } #declare Index = Index + 1; #end
There are some important things to note in this specific example:
