I use a few ruby scripts to match the cameras between sketchup and renders. I don't recall the exact names, camera controls? to get the tilt, pan and rotation.
I also use a script that places a construction point at the position of the cameras. I then draw a tiny circle at the point and paint a material named camera# onto that circle.
When I go into whatever render I am using usually Vue.( I can't get the script for Vue cameras to work) I place a camera at the position of the tiny circle that I exported with the model. I then adjust the camera orientation based on my camera settings I read from camera controls. I use the field of view setting from sketchup. Depending on the render you might need to adjust the angles of the camera. If camera control script said the camera was at -30 degrees you might have to enter it as 330 degrees in the render.
Hope that helps.

Griffith,
I am currently working on a water treatment plant project, everything in it, pumps chemical storage feeders, controls, etc. I spent several days searching for the fittings and valves. I ended up buying a cad library from cadtoolsonline. It was about $200, worth every cent. You will need to model the bolts. I just made several different rings of bolts for different size fittings. You can download the demo and try it out. Demo has up to about 6", full version up to 48". I checked to make sure that they just weren't scaled up from one size to another, doesn't appear to be the case. I'll try to post some screen shots of the fittings and valves soon. PM me if you have questions.

If you follow all of the links to the reserve page for the book, the release date is listed as November 24, 2008. Not September 2nd. Unless I am missing something?

silver_shadow,
Here are some sample pure sketchup animations I had laying around from the old google forum.
