Laser bolt glare problem in blender 2.9 So I'm trying to build a laser bolt like in Star Wars, and I added a cylinder with an emission texture. The problem is, in Star Wars, the laser bolts have glare, so I added a glare node in the compositing tab. I rendered the image with the camera, and there was no difference.
You need to use a higher value then 0 in you Mix Slider from the Glare, or the Glare wont mix in your Picture. This will make you Picture a little bit darker but the glare will be visible, you can counter the darkness with the Threshold Value.
