Sort_sop

[3__]

can't use variables and attributes to

offset point numbers in sort.

just wondering if is this a bug or a

limitation of sorting?

thanks,

Not sure I understand you. What are you trying to do? AFAIK, only the Expression parameters are evaluated per point/prim so that you can use local variables in it.

Try the reverse sop it lets you shift too. Is that what you mean?

ok sorry, try the following:

1. place a circle sop, set to poly.

2. append a sort sop, set to shift (points)

3. in the offset field type: $NPT / 2

for me this returns 'unable to evaluate... undefined variable'

same when using point() to grab $NPT from elsewhere,

and when using an attribute earlier set to $NPT.

As mentioned, only the Expresssion parameter is evaluated per point. It doesn't make much sense for the Offset parameter to do so because that parameter dictates the global offset. $NPT is a special case though as that doesn't change per point. Instead, you could use npoints(opinputpath(".",0)).
