Here is a little comparison between Arnold (with alShaders) and Octane. I'd like to achive same effect in Octane but I have no idea how. Thanks for reply.

Hi zsdani,
please could you post a screenshot of your material node tree?
In general for this kind of material you can use a specular material with high transmission and scattering medium, absortion white if inverted or black if not, white scattering and play with density until you get the desire effect.

Thanks for the Quick reply.

I'm trying to play the emission node too and of course changing the values but no luck.

Hi zsdani,
sorry, I forgot to tell you to activate the fake shadow option in the specular material:

the density value is a multiplier and depends from the scale of your object and it could vary a lot.

Thanks. Looks like it's working, but only when I'm using the PMC kernel.
