Vray issue involving reflections.

VVCephei

I am trying to render a reflective surface (the glass on a headlight) however vray's IOR is INSISTING on reflecting everything behind it 100% (with literally 0 control over that)

Here is what the surface looks like with an IOR of 1.51:


you will notice that the IOR is basically making everything behind the glass refract onto the surface to the point where it almost looks like a diffuse. However it still reflects the HDRI and I want to retain that.

And here is what the surface looks like with an IOR of 1.0:


That just looks like there's nothing there at all. It completely overrides the Reflection properties in favor of that one god damn IOR value.

How do I set up proper reflection parameters so that I can avoid this nonsense.

thanks in advance!

Is your headlight's glass just a flat plane or an actual solid piece of geometry with thickness? You'll need to model a solid object if you want your renderer to behave correctly.

Hey, thanks for the reply!

I'll give that a shot now. Will let you know if it works!

If you want control over your reflectsion too instead of IOR

Use the fresnel texture
