I have a polyExtrude node before a forEach sop. I've created a meta import node, which creates an iteration attribute. My goal is to iterate using the iteration attribute between the forEachEnd & the polyExtrude, remember the polyExtrude is before the forEachBegin in the network ?

detail(“../metaimportnodepath”,“iteration”,0)

You may have to do this in a channel expression because it needs to reevaluate the expression

Thanks, do you know how randomize a parameter, with expression; I tried rand() but you can't randomize a detail attribute ? I need to randomize a parameter while referencing the iteration attribute from meta import node of the forEach sop.
