its going to be an animation, but to cut down render times i'm using a still that i'm overlaying over a video clip in premiere, if you see what i mean. so i could photoshop the blooms if it comes to it, but i would prefer to get it to work without faking it with ps.
these are the properties i've assigned to the spheres, but they're casting shadows still
not sure which buttons to press. could you shed some light on the matter?
