Random switcher inside for each loop

[Fyre]

I'm trying to make a random switch inside a for each loop to assign one of four different noises to the primitive in the current loop.

I cant access $PR from inside the for each loop as its just looking at one primitive at a time, how can I get each loop to choose a random node?

If it helps the objects are in separate primitive groups before the for each loop.

 

Cheers

Hi, you can use an iteration number.

you can use the stamp() expression of this, for example: round(rand(stamp("../","FORIDXVALUE",0))*3)

stamp() should be avoided if possible, checkout this thread for for-each example: https://www.sidefx.com/forum/topic/51345/

Stamp really does not show a performance penalty until you are over a few thousand points. So it is still quite valid on lower point count geo. And even if you have a 60,000+ point object you can still leverage stamp() and just write out the result after the stamp operation. Place a FileCache node after your massive stamp operation to recover performance.

this was also a post of 2 years ago :P, a lot of us (including me) have already moved on to the new compilable-new-foreach-structure
