I am trying to group fracture pieces randomly in different groups so that I can split it further into small or medium pieces, but I want to keep track of the pieces.

How would I group it based on name attribute.

You can output groups in the fracture sop ie chunk_1 etc etc . So in many ways all you need to do is create a attribute based on the chunk number you want to shatter more

thanks for the reply, you mean voronoi fracture? how would I call it inside a group after it, for example if I wanted to pick a range randomly? and other range different from the previous range.

i figured out a way with attribute create and opdigits(@name)

Thanks for giving the solution to the problem which I faced.

Sounds like you found the solution you wanted, but in the name of completeness, a partition sop will do exactly what you want, ie, its purpose is to make groups based on attributes.

Eg, if you have a fractured object that has a name attrib for each chunk, you can append a partition sop, set the rule to $NAME, you get a group for each name.

Was surprised it worked with $NAME, but not @name, whereas the colour example works with @Cd. Oh well.

thats nice, thanks, so can I select random groups, because its a string anyway, what would be the expression in delete sop afterwards if I use partition sop?
