   You take a look at Photoshop blend mode math? Link From the hlsl code: define BlendColorDodgef(base, blend) ((blend == 1.0) ? blend : min(base / (1.0 - blend), 1.0))

   The setup is correct, but the material shouldn't be applied to your meshes because it's using the Post-Process domain. It's only meant to work as a "Blendable" inside the Post-Process Volume. When used that way, it'll Color Dodge blend the color with your final scene color. Because there is no simple way to mask out single…

   Basically the T_Test.png is a test sprite of a Light Beam and it should be processed as a layer in a ColorDodge mode in PS. So you're saying material+node setup should be something like this: Then I should apply it to any sprite I want to work as a ColorDodge layer in PS? When I try to do it, sprite just become transparent…

   Compared to the Photoshop layer setup, base = bottom layer, blend = top layer that has Color Dodge set as the blend mode. Some of the Blend functions in Unreal have different input orders for Base/Blend, so it's possible that you just put the wrong textures in the wrong input. The only issue I can see with the material…

   So you're trying to Color Dodge the color, or in your recent example the PNG, on top of whatever is in the scene? It looks like you were on the right path then using the Post-Process shading model. The only issue is the SceneTexture node should use the PostProcess input. I forgot the name, but there's a couple of them,…

   So we are trying to achieve a similar effect to Color Dodge Blend Mode from PS for some of 2d sprites in our game. We've tried using Blend Function - Color Dodge and all existing Blend Modes, but for some reason it just doesn't do anything similar to PS. Any suggestions on what we are missing? Or maybe another approach we…

   I don't have the editor open right now, but chances are that the function is already doing this, however you can give it a shot yourself just to be sure. "The Color Dodge blend mode divides the bottom layer by the inverted top layer." - taken from the Wikipedia page Edit: It seems to work fine for me and gives me a near…
