Hello, I have a high school student who did something to his mesh I can’t figure out. I’ve attached 3 pics. He built a lighthouse mesh. The camera points to the mesh. The camera view shows the lighthouse in it. When we render that frame, we get a background with a dot of light.
Yup, with your version, he has clicked the object button (f7) then clicked the particle buttons button, then selected add new, the default setting for the new particle system would have the effect you see. Click the X next to the particle system where is says PA:PSys.001 (the default name) and it should be okay.
