Depth Fade: Calculates distance to any opaque objects behind it. It is used to hide unsightly seams when translucent objects intersect, or to blend visuals based on the depth. It takes two inputs: Opacity and Fade Distance. It outputs the Opacity value fading to zero once it's in the range of Fade Distance. #unrealengine #ue4 #ue5 #shaders #materials #gamedev #vfx #techart #indiegames #tutorial #howto #unity
