The Subsurface shading looks incorrect in the Blueprint Viewport window. Adjusting the cvar for r.sss.checkerboard from the default value of 2 to 1 looks more correct and a value of 0 switches back to the incorrect look.
This only affects the Blueprint viewport and does not appear to be an issue in the static mesh editor or main viewports.
1. Open QA Game
2. Add the static mesh "Head" to a Blueprint
3. Apply the material "Skin0" or "Skin0_Inst" to the static mesh
4. Open the console and enter "r.SSS.Checkerboard 1" (default is set to 2)
Results: The SSS does not look correct in the Blueprint Editor Viewport.
