Reflections: would like to know how to....

[roy]

I am looking for some insight in how to create reflections that are not complete sharp mirrors but smooth and gradually disappearing ones (like the ones in GonzaloP's posted rendering in the photometric lights topic.
Thanx in advance.

Two settings are involved, both are found in the Vraymat. first is "glossiness" in the reflection area you will see a spinner anything less than 1.0 will unsharpen the reflections (using interpolation will speed this up). Second is fresnel reflections, checking this and setting the propper ior in the material will make the reflections "falloff".

Works!
Thanx ReRender!

hey Rerender, with the IOR for reflections are you saying that you change the IOR value under "refraction" and that affects the Fresnel fall off for reflection?

[GoncaloP]

Yes, the IOR affects the reflections too
