I Nuno,
as already explained by FooZe a long time ago, there is not a multiple IOR option in Octane right now, so there is nothing that could be fixed ;)
Let's see when OpenSL will be full supported if there will be some news in this aspect, but for now, you have to wait :)

Ok. :)

Sphere looks to seem be true. But cobbled oblique (and cube?) fake because the extraordinary ray isn't supported (=is processed badly) but the ordinary ray is processed well. :)

What's OpenSL? I don't understand it.

See new manual here. :)

The sphere rendered at double ior looks fake using current version of OR, sorry - but on tonight I've studied this PDF, ;)

New OR v3.1 will support birefringence due to the OpenSL added, ok??

Birefringence is very important because by example: clear plastic (not glass) material HAS phenomenally cyan and clear violet little visibled. :)

I've wanted us to look into polarization of light at some point, and we'll try to see how far we may get with 3.1 OSL (as a first step in exposing some parts in the material system).

Good. :D
