It's the lame question time:
I have a curve, and I recall, I could reverse the direction using the Reverse SOP node. Now I cannot do that, apparently. Does anybody have idea?

Perhaps you want to use Sort SOP -> Point Sort (Reverse)?

To reverse the point order on a curve just use a Sort sop and select reverse from the point sort parameter dropdown.

Damn animatrix_ beat me to it

To properly reverse the curve you should use Reverse SOP
And then you can use Sort SOP in By Vertex Order mode to have points reflect it if you care about point numbers

Another method was to remove the N attribute, reverse SOP and reorient the curve in question. Interesting, if I don't have an explicit N attribute reverse SOP works
