Hi everyone,
sorry if this is really a stupid thing but i was trying to have an add sop with the same number of points as there are primitives in another sop, now i can't seem to get this to work i try to insert an expression in the number of points field but it doesn't let me type anything there. I tried using ‘alt + e’ and inserted the following:
nprims(“../curves_grp”)
Where curves_grp is a group of curves, but the expression doesn't stick when i get out, if i press ‘alt+e’ again there's no expression there. Is this something i'm doing wrong or there's no support for expressions to define the number of points in Add SOP?
Another thing, i think it would be useful when dealing with expression functions to have some variable to automatically reference the input SOP, something like $INPUT or $PARENT that could be used by any expression even if one changes the node input. Not sure if something like that exists but i think that is probably easy to achieve if it doesn't.
Cheers
