Exclude geometry from the octane sun/sky? Tweet

[heartlessphil]

I haven't found how to exclude my background plane (city landscape) from my octane sun...sun is blocked and won't lit my interior well. Is this feature even in OR 1.20?
Thanks. I guess I could add it in post but I'd prefer to do it all in 3ds max.

Also, any special tricks to enlighten an interior? I just have direct sun coming by 2 big windows with architectural glass (opacity 0.5). I'm rendering with PMC and my maxdepth is set to 8. Still kind of dark im my opinion. Sun is set to around noon, facing windows directly. Should be bright!!!

Very impressed with the the soft shadows, translucency, reflections, octane can produce!!!

Try using a specular material for your glass and enabling the "fake shadows" option in the materials settings.

If you have setup an actual background plane as geometry in your scene then you will not be able to make this "see through" to the sun. (Octane can't do this).
A couple of alternatives are to use an HDRI or compositing in the background later by ticking "Alpha Channel" in the kernel settings (and making sure "keep environment" is off).

Ok thank you!
