Hello All!
How would I make an object, say in this instance a wall, be invisible to camera but included in light an raytrace calculations? I want it to block light, cast shadows, and appear in reflections but not block the camera view..

...and your render engine being...
Create>New Iray Section Plane, select it, turn on Clip Lights in the Paarmeetrs pane, and position it to cut off the wall but not the things you want to see (treat it as extending to infinity). If you can't do that because of the way things are placed I'm not sure there is a way to do it, though Light Path Expressions in Canvasses in the Advanced tab of Render Settings might be worth checking.
