I don't know if I should post this here or just mail the Glare guys, but I've been aware that they're on this forum as well, so maybe it's worth the shot:
I'm trying to build a demo scene with some particles, but I've found a problem when I use the demo presets they kindly offer on their repository. I have a stencil mask that emulates the final configuration my client is looking for - a big screen in the middle and two little ones on the sides - and all my content is just shown within the boundaries of that stencil. But I just don't know how to make the particles to show only on that stencil.
I dont' know if it make any sense to you, but I'm hoping for you to help me!

Thank you so much in advance.
