Title: Disable corona IOR in c4d
Post by: tensai83 on 2019-05-28, 11:36:00

I see, in 3ds max, is possible disable corona IOR to create phisically correct metals. Is it possible also in c4d?

To disable Fresnel IOR, turn to value to 1.

To disable fresnel, you have to crank fresnel IOR to maximum - 9999 By setting it to 1, you'll effectively disable reflection.

Is this about reflection or refraction IOR?
Why disabling it would create "physically correct" materials?
