Point tracking to hide particles behind objects?
I have a steadicam circling shot where I've added atmospheric particles. I would like to hide some particles behind trees where appropriate. So far, I've been able to use the HitFilm point tracking to follow some particles. I also have the same live action shot without the particles in a layer "behind" the shot with the particles.
What I would like is to create a mask at the particle (tracked point) and keyframe it to create a "hole" in the front layer, so when the particle is to pass behind a tree the "hole" shows the layer behind without the particle.
Now that I have the tracked particles, what is next? I need to add a layer to the particle right? What type of layer? Which "effect" or mask do I use to simply make a hole in my current layer?
