I am trying to achieve a glow effect in the UI, but I can't figure out how to do it. Even after setting the color parameters to a high value (like (30,0,0) as I do normally to achieve this effect in the world), it stays the same. The effect I'd like to achieve: https://ray3k.files.wordpress.com/2016/08/preview1.gif?w=840
The UI elements in your example image are most likely just texture files and the glow effect is already in the texture. The glow effect that you achieved with setting the emission value above 1 is caused by bloom, but that does not work in UI so you have to bake the glow into the texture itself in a image editing software.
