I fractured an object. Not for Sim though. I'm trying to figure out how to randomize the scale of the pieces of the fractured object. Any ideas?

If you add a “For-Each Connected Piece” into your SOP network, a connectivity node and a for loop block will get placed down. The connectivity SOP will assign a unique number to each piece of connected geo and the for loop will run through each one individually. Add a transform SOP inside the for loop and set the Pivot Translate to $CEX, $CEY, $CEZ to move the pivot point to the centroid and from there you should be able to do whatever you want with the scaling of each piece.
