I'm trying to recreate the light of a movie from a super 8mm projector hitting a cube, so the light stretches over the top and falls off completely at the sides. I've tried using an image as an emitter there is no way of focusing it. I can also see no way of adding an image to a light source in blender. What's the best way to get started with this?

$\begingroup$ You can use a plane with an emmision shader and shape it in a way that focuses the light in the way you want $\endgroup$– The KalaakaarCommented Aug 10, 2023 at 12:37
