Hi;

In a SOP, I would like to use the prim expression function (https://www.sidefx.com/docs/houdini/expressions/prim.html), but I don't know how to retrieve the primitive number. I mean in this expression:


Can I use $PR instead of number 3?
I think I can't use @primnum cause this is an expression, right?


Thanks for helping.

Hey man!
If the node which you're trying to write this expression supports local variables ($PR in your case), you can use it otherwise no!
