Fresnel Reflection Bug?

V-Ray V-Ray for 3ds Max Issues
1

Hi,
Not sure if this is a new one or not, but when using the Fresnel Reflections tick box, it appears not to work when a Opacity map is used with in the material (1.50.00).
Using a falloff map in the reflect slot works fine though.

It’s not a bug; it will work if you un-lock the Fresnel IOR from the Refraction one.

When you have an Opacity map, V-Ray assumes 1.0 refraction IOR for the material.

Best regards,
Vlado

Cool thats ok, I hadn’t noticed this in previous builds.
Cheers.
