and set Reflect Objects on your material otherwise rays that hit any object(or self) will be black unless environment has shadows off as Skybar suggested

I tried Fresnel reflection with specular minimum 0 and 1 with shadows off in environment light.
Turning on Reflect objects gave a better result but still have black areas.
I did some renders with different settings. Please check them.

Seems to disappear if you toggle off “Clip to positive Y” and turning off shadows on your light.

Nope, its not working.

HI

I have problem with the reflection on a displaced geometry with Very strange dark artefacts. And I'm not getting full scpeculars with the HDR lighting.

Ocean deform tool in 12.5 version is used to create the ocean surface.
I am using PBR rendering,and mantra surface shader with no diffuse.

Iam using HDRI from here

I have attached the hip file also

I wanted the full speculars…but its making bright ring around a black spot.

Thank you
