Hi. I just purchased the Audio Visual pack.
The first time I applied the Atomic particle effect to a layer in a composite shot, the particles showed up just fine. However, it was causing Hitfilm to lag and freeze, so I decided to start a new project from scratch and try again. Upon starting a new project and doing the exact same thing as the first time, no particles appear at all, no matter how many settings under the atomic particle effect I mess with. Since then, I've returned to the first project where it worked the first time, and have found it no longer works there either. I've restarted both the program and my computer.
Here is what my main timeline looks like, as you can see, the composite image is the only thing on it:
Here is what my composite shot timeline looks like, with the Atomic particle effect on the layer (unexpanded):
Here is the Atomic particle effect expanded. No particles show up in the viewer no matter what I change in the drop-down settings:
I'm baffled as to why this worked once, but not a second time. Is there something obvious I'm overlooking?
