I just tried it but it doesn't work, when i minipulate the object itself it follows. But when i keyfram the object the outline stays where it is. I have tried the same thing in maya 2014 and apperently it does follow the keyframed object there.
OH LOL. this is how it works. jesus i totaly forgot. this drove me up a wall the first time. when you have 2 objects and you want to merge them, xsi creates a 3rd object that is the merged one. it leaves the 2 objects as they are in case you want to go back. haha with it's history saving feature and this whole thing, it's…
Simple! Select that object, right-click it, then select "Object Properties". There's the "Backface Cull" option on the left, just check it and your'e done!
Fantastic, huge improvement on those rocks! The silhouette for objects is very important - as it is the first thing that the brain uses to identify said object.
