UE 4.27 - TAA - blurry Translucent materials with “Disable Depth Test”

Hi Everyone.
We get blurriness when we render translucent materials with Disable Depth Test Enabled, and when these materials have other opaque geometry in front of them. The issue is in UE4.27.
BTW, The situation is very similar with DLSS / FSR . That makes me think it could be connected to the engine’s render pipeline and C++ tweaks are needed … ?

  • Quite visible in the Editor.
  • not so visible, but still there in Standalone Game mode
  • Replicatable in both Forward Shading and Deferred.
  • Output Velocity for the material is Enabled
