antialias works nice, mostly.
I use PBRMaterials, reflecting the sunlight (as DirectionalLight)
and only at certain flat angles the sun gets reflected remarkably, as expected.
But the reflection causes Moiré patterns.
engine.setHardwareScalingLevel(0.5) does help but increases the render time. My fan starts running.
pbrMaterial._enableSpecularAntiAliasing = true; or
pbrMaterial.enableSpecularAntiAliasing = true; did not show any difference.
A more detailed texture will help, but cause other loads.
Is the antialiasing function used for the reflections?
Scaling = 1
Scaling = 0.5
