Bright spots appear when using concrete_slab material from Megascans and lighting it with night HDRIs from HDRIhaven.
When it's a flat environment light (no IBL), or the IBL is daylight, I don't see the bight spots.
The HDRI texture map is defined in File color space as [Utility - Linear - sRGB]
Any idea what might be causing these?
I attach screen prints of the night HDRI render (using moonless golf HDRI), then the day HDRI render with no issues, then the original material from megascans.
