Hi,

I would like to know how can I turn off and map the IOR in Cinema 4D/Corona, like in 3ds Max/Corona or Vray.
I want to connect a bitmap or any value with the 1/IOR method.

Thanks in advance.

Hi! The IOR texture slot doesn't work for you?

Hi!

Thanks for your answer.

The IOR slot is perfectly fine. What I don't know how can I turn off the IOR number(like 99999 in Max) and control it fully with an 1/IOR map.
I tried different settings, but it not works like it should(Max/Corona or Vray).

Okay, before I posted this, I tried it again and it seems I figured it out.
I have to set the IOR 999 at the maximum to turn it off, and the 1/IOR map needs to be inverted.

Can you confirm that this is the right way?
Anyway why do I have to invert the 1/IOR map? It should be consistent in every application.

Thanks.

Ps.: To be honest I'm not a C4D user, just tried to help to a friend.
