Title: Ior texture: remap values in [0, 1] range
Post by: Nicolaswi on 2015-08-01, 12:51:40

Hi,

For the moment we can use a texture in the IOR channel, but the values have to be > 1 to be taken into account. So an intermediate process has to be applied to get hdr values from a 8bit texture.

Vray does a smart thing: the values < 1 correspond to 1/IOR. So a IOR of 1.5 is equal to a IOR of 0.666. It's a lot easier to use a texture for ior this way :)

What do you think ?
Nicolas
