Yep, it doens't work. It's a techical issue since you can create in this way a IOR cyclical loop. We must think more how to implement this safely. Until then you can use the 3ds Max version of VRayMtl - BRDFVRayMtl.

Thank you!

There was a method of using VRayPlugin.
It solved.

Could you give us more details on how would you expect this to work and what you are trygin to achieve?

I asked the customer. (reported this problem)

He said that refraction IOR is well used when making a mirage effect.

Thanx

Is this planned currently? It has uses, for example, imperfections in glass.
