Hi,
about glass, in Octane you need to enable the Fake Shadow option in the Specular material, but you also have to add thickness to your glass (1cm or less), or it reacts like a magnifying lens.
If you don’t want to add thickness to your glass, you can use a dark Glossy material, with Falloff node ...

There are some issues with converting translucent materials as they have a bunch of quirks that we have to approximate.
The new build will have a few fixes that might fix this issue, but for now we advice using the octane materials for glass and translucent materials.
Would it be possible to share ...

I vote for this to be the official way to do this lmao

Hi,
First of all, excellent plugin. Doesn't feel like a beta release at all.
Some feedback
a) Glass materials seem to have an issue.
This is with the window glass object set to visible inside the editor

And this is with the window visibility turned off ...
