Can you post a screenshot of the glass material setup pls.

Hi guys

The material looks like this:

The two options that are below the edge are film width: 0 and film IOR: 1.45

One thing thou - that I think has no effect - is the absorption medium - is set to black so doesn't absorb anything (it shouldn't be there, I think that v3 adds it by itself (materials were created and saved with v2))

Fabrizio: is your glass geometry built form two faces or just one plane?

Ok I think I know where is the problem and how to fix it.

The live geometry setting is ok - problem is that refraction (which happens with specular material) - bypasses the "visible to camera" setting (that is probably due to its involvement in GI calculation etc).

To over come this effect - instead of specular material in glass use standard glossy material with black color, IOR set to 8 and lower the opacity. You get the reflection, but the plane is not visible.

That is the only way I believe

Hi Mac and thanks a lot for your suggestion.

However, I think it would be better to fix this problem in the next version of octane.

It would be really good if Live update could work with work session files. Not sure how you would implement that.

Hi - turn Smooth OFF - since the glass needs to have hard edges in order to render correctly. Also make your the Kernel->Ray Epsilon is less than the thickness of the glass. https://docs.otoy.com/manuals/products/ ... ayepsilon/
