Render Tag Caution (with Fix)

Just an FYI for anyone else that might come across this issue.

So, I've been racking my brain for a few weeks over this issue, and I just figured out what is going wrong. Objects that are children of another object that has a Render Tag applied, will inherit that Render Tag's settings. I have an opaque purple suction tool object attached to a clear material and have a Render Tag on the clear material so I can exclude it from Radiosity. My suction tool was coming out rendering really dark and I tried all kinds of stuff with the lights and render settings trying to fix it. It finally dawned on me today my that my suction tool was inheriting the settings from the Render Tag from the parent object. The fix was to apply a second Render Tag to the child object and turn on all the check boxes. Now it renders correctly.
