ok mate thanks for your help i will give that a try tomorrow, is that all there is to it? It just seemed that particular was ignoring the fact that I had rotobrushed out the video (which was standing -10 on z axis) and was being obscured once it travelled behind -10z regardless if that area of the video was roto’d or hidden. Other than that everything on particular was working fine.

Sorry to rabble on, its just that I couldn’t find anyone else on the internets who had come across this problem, perhaps I am using an unreliable method?

Hi John,

I dont have the aep file at the moment but i can upload an example project of what i am trying to do. Basically I need the “obstruction layer” to only apply to the rotobrushed area of the layer.

Because the rotobrush hides the unselected area but does not actually delete it, the whole 1080×720 layer is still physically there, only certain areas are visible.

The example on here is what i am trying to do, only the red box will be a rotobrushed person on a seperate layer.
