I want to darken my background image, specifically my character selection scene, and have a light node that lights up per selection choice of my character, does anyone working on the same idea and know how to help me. Much thanks!!
Not sure, most likely shaders. That is under material, NewShaderMaterial.
light 2d might be able to do the light up feature. as for going dark, shaders can probably do it or a cheating way would be adding a black color rect and decreasing the transparency
use shader for a better effect. you could cheat and use a colorRect and set it to be grayish but that would not look as good as a shader
