[Sidefx-houdini-list] Rman VOP displace shader

I've built an RMAN VOP displacement shader using the VOP aanoise.  When 
I animate the camera, the noise moves.  So I added an rsl_transform 
node, from "current" to "world". Still moves.  Tried an in-line VOP with:


... no joy.  Tried:   vtransform("current", "world", P);

... no joy.  Then I tried to pipe the first transform above into another 
in-line VOP with

noise(pp*10) * .2;

... and it works, the noise sticks.  Is the Houdini RMAN aanoise VOP 
broken?  (I see lots of space change warnings in my .err files about the 
voplib.h files.)
