QUOTE
id_inclexcl defines an object instance label (set with the tag keyword of the object instance in the .mi file) to be included (or excluded) from being considered occluding by the shader. Set to 0 the parameter has no effect. A positive integer means that only object instances with a label that matches this number will cause occlusion. A negative reverses the condition and includes all object instances except those with a matching label.

I want to prevent one object from occluding itself. I read the above but I don't understand what the hell is an "object instance label"?

Its a custom attribute you need to add to maya objects (its basically just a id number). Its not documented in 7.0 but it is in newer mayas so go to alias site and reefer to the 8.5 manual

Oh and by the way pass custom labels must be on in the render globals.
