Why is my specular reflection missing from my image?

The specular properties of the cylinder are not seen in the reflection.

Thanks,

Theo

It looks like its something to do with the Exposure (and Physical camera) control you are using. I also noticed you are using a Physical Sun & Sky Environment. I replaced it with Arnolds Physical Sky and it seems to behave correctly.

I changed the Specular Ray Depth to 16 and it made no difference. I would like to send my sample file if I could.

Can you post your shader settings for the plane? Is the Specular Ray Depth high enough?

Could be a to high of a ev value?

The first one is at 6, the second at 16 + a bit of light compensation.

Maybe upload your test file. ;)
