so from the picture, im having an issue, i did a tutorial using compositing and cycles to get a light saber glow effect, my goal is to have the blade red, with a red glowing effect to mimic a light saber, but as you can see something went horribly wrong and cant fix it, please help!!
Have you tried using the compositor’s glare node at all (it has a general bloom filter labeled ‘fog glow’).
Don’t forget to have a separate node branch to extract the bright spots of the image (so the compositor knows where to apply the glow).
