How do you use the function SEED with a RAND fuction?

When you call a random function, it returns a random number from a set of random numbers. If you have a random call in an animation eg in an expression, every time you play back the animation those random numbers will be different. If you set the seed, using seed(x), where x is some number at the start of the animation, although the numbers chosen throughout the animation will be random, when you play back the animation those numbers will be the same each time.

You can set this for the animation using an expression such as,

if(frame==1) seed(7);

then any value using rand (or sphrand and gauss) will be randomly chosen, but consistent each playback.

Hope this helps.
