I’m putting together a series of lessons for my sister so that she can learn about meteorology and I just got finished with my first animation today. The problem? To describe what I am trying to create, I used a picture of the sun (through Gimp I just made a ball of light yellow), a picture of the earth I found online, an arrow to indicate direction of heat flow and finally a black background with noise so that it looks like stars (also made through Gimp). Now the problem I’m having is that even though in the editing window I clearly see the starred background as I play my animation, when I render it the stars disappear–I want the stars in there to add depth but even when I tried rendering it into a video file the animation was missing the starry background. I just recently learned how to do 2d animation with a set of pictures so I have no idea what to do. I’ve attached a screenshot to give a better representation of my setting; in the animation, the only things that are animated are three red arrows that travel a mostly straight trajectory from the sun into the earth–that’s it. The stars appear here but not in the render.
Thanks for any help you can give.
