Can controls change propeties?

Scavenger

Is it posible to have a control on a model that can control it's own propeties, like Opacity level as a for instance?

AS in, in the paramenters tab, where you might have a "open door" slider that changes some settings on a bone, can you have one that changes a setting on a surface?

Perhaps, but I'm not sure it would survive a save and reload. There isn't a way to do it in the UI, but at least for numeric properties on surfaces it should be possible to use a script to make a link.
