I was wondering how to create a material that I can use inside of UE, that behaves like it’s on a layer set to SCREEN Mode… like you maybe know from After Effects or Photoshop.
You can use a material that is translucent.
In the material, you use the “SceneColor” node, this is the color of the pixel behind (in PS that would be your bottom layer) your mesh.
You can then use the Screen Equation 1- (1-a)(1-b) where a is your texture and b is SceneColor
