For my Halloween setup, I wanted a quick way to address all my RGB effects (not nodes but things like floods) and be able to apply an effect to all of them. I created a Model Group and added all the Elements that had RGB components. I then made that model available to my sequence display. I applied effects and it works great. When I save, it seems to save fine. The proble is when I go back into the sequence, I get messages for a bunch of my elements that says: "Could not find a model or group names...". It then proceeds to list a whole bunch of models and elements. Most of which are not even in my sequence at all.
Any ideas?
