Maybe you might already know, but if you don’t, just to let you know !
If you ever use a CC Power pin effect on a 3D layer, just make sure to apply a default Corner Pin effect right after (just apply it, you don’t have to change any value).
Otherwise the the 3d layer will just disappear.
So if you do your project on an earlier version (and use CC Power Pin in it) and if a buyer opens it on a CS6 … well you know the rest 
Its a bug …, but with Corner Pin trick you will be fine for now …
Refer to this thread for more info on this problem.
