Hi all.
Here we go again.
I don't know is it a bug or a feature...But i love Specular material more and more.
Just changed "Plane Orientation" from +X to -X.

It's expected. Needs normals which are pointed toward out of volume.
Don't use planes, use boxes if you want exact same glass effect.

What a you talking about ? Volume object ?
This is not a volume it's a simple 4-point polygon plane with glass material.
Download scene file please.
Other renders don't have this problem (i-ray,c4d render,arnold render)

Ok can you please ask in general forums? That's not about plugins.

Thank you for response. The problem is not related to plugin or Octane.
It's a C4D problem of screwing up Normal direction of polygon when using "Plane Orientation".

I just was surprised that other renders can handle it easy without artifacts.

So apology for a harsh post.

I don't think there's a bug or problem on plugin. It just normalizes the normals how you tweaked.

I want to go even further, for me it's a feature, we can have negative volumes, air volumes inside fog volumes, infinite water planes and optical simulations thanks to this "feature", just to give some examples ;)
If you don't need this, just use a glossy with falloff opacity.
