Fresnel reflections

[comput_cg]

I?m not sure if this is a bug and it?s pointed out before, but here is some images which I?m not sure why they are behaving strange !?!?
It seemes like the MAP-image is not rendering out if the ?Fresnel reflection? is not turned ON?
You can see the image nr. 2 have the same settings as the image nr. 3 but the ?Fresnel reflection? is turned OFF on image nr. 2 ???

Best regards

Comput,

In image 2 if you want your map to show and you want reflections with no fresnel you must make your reflection color closer to black. Right now you have made a 100% mirror if your reflection color is white.

Fresnell doesn't mean reflection, it is a property of reflections, so turning it off doesn't mean you'll get no reflections.

scroll down for "fresnell and ior", that should clear things up!
