[Sidefx-houdini-list] N in VOPs

Did you know?

In a VOP SOP building context - if you modify P, points that have no surface
(particles etc) will have their N attribute automatically recomputed to
{0,0,0} ?

... Unless you explicitly wire the input N to the Vopnet output. (In general
attributes going through VOPs will not have their values changed unless you
ask it to happen.)
