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.

I'll upload video soon about my clear plastic (90% transmission) tomorrow...
