Hello,
i'm currently working on a project where i did a sand simulation. That worked.
But now i only want to see the top plane of the simulation, so that i can place it my video footage.
The Sand is placed in a box and then a character comes through it and some of the sand goes up. Now i want that at a certain y-value the sand is not visible anymore and i can place it in my footage.
I hope someone can help me;)
