So i tried gooogling and asking around in discord servers but no one is really helping nor understanding what I need.
To sum it up, I need an object to LOOK like the sun in 3d space, aka it needs to be very bright. "just put an emission shader on it duh!" well there's a problem! I have cell shading and the size of the object depends on how smooth the shadow is! So if I have one light source which is huge, casting a very huge smooth shading all over my cell shaded objects, it just looks weird.
So - a fake glowing object. I just need an object that looks like its glowing but does not cast a shadow. That's all.
