How to Have a BLOOM/GLOW Effect on Actor (Shaders)?

[Kan3x]

Hello guys

While trying to get my Sun, in a day-night cycle, right I stumbled upon a few issues, with one of these being: how can I make my Sun actor not to look like a simple slapped png, but to look like a proper (fake) light source?

I just discovered the existence of shaders and, by the look of it, it should be easily possible to attach to my sprite a shader so that it can have a cool bloom and/or glow effect, but I’m completely clueless on how to do that.
I’ve already downloaded and looked into the shaders catalogue in this forum, to study them a bit, but I can’t really grasp “blooms” or “glows” (I actually got a cool bright glow effect using the “HUD elements glow” shader, but I clearly messed it up too much cause my fps died in trying to render the ultra-shiny sun I obtained).

Can someone help me with this giving me a solution, a right direction, please?


P.s. First things I tried were, obviously, simple “add” render style, fake-bloom semi-transparent sprites and actors etc., but unfortunately I had several issues with rendering multiple actors with transparencies

Couldn't you use brightmaps?

Unfortunately, brightmaps have no use in this scenario, they only light up specific parts of a sprite, while I need an actual “light aura emitted” by that sprite.
