I had two layers with particular on them in this project. Later, I noticed after creating them that there was a new spot light created too.
Later, I pre-comp'd a group of layers with these two and the light. But somewhat afterwards I noticed that 1 particle layer was no longer visible. (I mention the light thinking this possibly has something to do with it?) Yet the other layer is visible.
If I reset the effect, it is visible but I have lost all my settings and key-frames. What is making this effect visible-invisible? Did something get lost when I pre-comp'd?
