Color Burn Blend over Scene Color

I decided to test things even more simply: by only using a 50% opacity white. That way the blend modes aren’t getting in the way of figuring out exactly what’s happening.

Here are my test swatches:

  1. UE simple material (unlit), solid color #FFFFFF80
  2. UE new Material Designer material (surface, translucent, unlit) with one layer #FFFFFFFF, only that layer is set to 50% opacity
  3. UE new Material Designer material (surface, translucent, unlit) with one layer #FFFFFFFF, entire material is set to 50% opacity
  4. UE custom material (surface, translucent, unlit), Scene Color and solid white lerp at 0.5 and passed into Emmissive Color
  5. Photoshop solid white (normal blend mode) at 50% opacity.

#1, #3, and #4 look identical to me. There’s something funky going on inside the Material Designer in #2, but we can disregard that and focus on the others.

#5 is what they should actually look like. A straight 50% blend of white on top of the background. Also confirmed with Figma.

The new Motion Design Mode creates a PostProcessVolume that essentially neutralizes everything. 0 bloom, 1.0 exposure, all color grading unchecked, etc.

Any idea what could be causing this? I’d like to be able to follow brand guides exactly when creating graphics and know that the colors are to specification.
