Hi, I started PI very recently and I need help with one thing. I followed one of your emitter loop tutorials to make a little loop thing of a sparkle that I had made. I made everything perfectly and when I view it in PI, it looks fine just like it should. But when I export it by rendering it in a .png sequence, only the actual emitter on the layer shows up and not the background images within the layers. Can you help me figure out what I did wrong, or possibly how to edit my preferences in order to have the correct result with the background images inside the render. Thanks.
