You can use the global variables $T, $F and $FF to drive your offset and animate over time.

Always helps to post a file. Machine specification is interesting as well.
The fluid particle surfacer creates a lot of polygons. Doing a polyreduce might decrease rendertime a lot without any quality loss.
Also switch to PBR or Micropolygon rendering. The ray tracing one is slow.

You could just keyframe the birthrate.
If you wan't to use expressions this
if($F>=250 && $F<=300 && ($F%2==0),1.0,0.0)
works.
I use it for the Const Activation.

I think you can disregard the warnings. It loves to spit out those errors and usually it works fine anyway.
Your concern is probably the line
mantra: Displacement shader ‘op
obj/shopnet1/pc_occ_material1’ doesn't seem to compute N.
I have had a lot of problems using the occlusion VOP for displacement and don't remember if i solved it or did it some other way. A file to look at would be fun.

The $OBJID will be the same in each channel for the same object. Therefore the rand expression will use the same seed and always return the same result.
On the File part i haven't had any problems like circusmonkey but usually prefer to use the ROP Output node instead.

Contains a VOP network that can manipulate point attributes.
Use a transform node together with a switch or something.

A lot of ubuntu users have switched to Linux Mint. Based of Ubuntu but still running gnome2. Houdini runs perfect after doing the fix and i guess will run perfect without it when a build on gcc45 is released.

Create an attribute with your point id and bring it in with a regular parameter as you would do with any attribute.

Make sure you are running the exact version of Houdini that the RealFlow plugin is built for. Can't help more than that because no access to RealFlow myself.

Try removing your settings folder for houdini11.0. Should be somewhere in Documents and Settings if running Windows (best guess).

Install mencoder and ffmpeg. They should be in the repository of your linux distribution.
Then export should work.

hip files or video makes it so much easier to help. Probably your motionblur settings aren't correct.
