When a grayscale map is assigned to vraymtl's refraction IOR slot, what will happen?
What should I do if I want the black area to have IOR = 1, white area IOR = 2? I tried to change the IOR when there's a map, the IOR value seems to be ignored.
I checked the chaos documentation. It's not mentioned there.
I did a test with VrayColor. When the map's gray value varies from 0-255, the IOR varies between 0-1. So how do I use a map to bring an IOR to above 1? Thanks again.
I also checked lots of info. No materials have IOR between 0-1. Most things have IOR between 1-2.x. Since then, what's the purpose of having this texture slot for IOR, if it can only be set to 0-1?
Any help will be much appreciated.
