Hi, I’ve been checking out the nvidia branch of Unreal - the current 5.5 version and I have this weird issue. Whenever I try to make a mirror - a material with 1 in color, 1 in metallic and 0 in roughness, the reflection is destroyed by a crazy bright firefly white glow, all over that surface. The issue dissapears when I set the roughnes to something like 0.03, but that also makes the (already blurry from raytracing) reflection even blurrier. I am trying to make a working mirror. Does anyone know how to solve this?
set r.Roughness.Min to .07
and r.SampledLighting.Indirect.MaxSpecularIntensity to 1
should be working fine :]
