OTOY Forums

Hi,

I have a problem with transparency not propagated through glas. I think I read somewhere in this forum, that this is some kind of octane limitation, but a friend of mine achieved the effect I want with a fake glas shader (glossy-specular-mix) in octane for modo. I tried to reproduce his solution but never got his result.

Am I missing something or is it in fact a limitation?

Kind regards

Carsten

Hi Carsten,

Yes, you need to use opacity for this. If you don't care about correct IOR and you are happy with just a mix of reflection and transparency, then just use a single plane of the glass, apply a glossy material that is like a mirror, and then control the opacity with a falloff node/map. When you tweak the falloff map, you should be able to achieve a blend of see-through when viewing the window face on, and reflective (mirror-like) when viewing at grazing angles.

Hope that makes sense!

Thanks
Chris.

Hi Chris,

thank you very much for your reply. Now I know for sure.
I will try to use the setup you described. As long as it looks good, I don't care about IOR

Kind regards

Carsten
