If there is an other post with this problem I'm sorry, I didn't see it, I will delete this if there is one.
I want to create an animation of two meteorites that are collapsing one in the other. I did a composition in which I put some layers and I gave them the particular effect and the emitter was a light layer. Because I want one to be red and the other blue I tried to make a composition for the red and one for the blue one. The problem is that if i pre-compose them and put them in the same composition or nest the two compositions in the main one the axes and the entire movement go crazy. Nothing moves as it should. Any idea how to fix this ? This is because the light layer or because the particular effect ?
