Sided polygons

[MichaelT]

Hi,

I've been meaning to ask this for a while. But now a situation arose where it became necessary.
I have a camera behind a wall, that is supposed to be single sided. So that I can film into the area,
but not let any light etc.. stop bouncing off the wall that really is there. A.k.a single sided polygon.

But it appears that Octane regards all polygons as double sided regardless. Which of course poses
a problem. Because I must now remove the wall, or place the camera in front of it.

Is there a way to fix this?

Hi,

One solution could be group all the walls that you want to hide in one object (or object layer) and enable the "unseen by camera" flag in the objects properties panel.

Thanks,

Hi ! In camera node, you can use near clip depth value too !
Have a nice day !

That kind of setup works great too, I used it before

I wanted to be helpful and tried that same couple of hours ago but didn't get it to work so I didn't post it
It worked manually by setting the amount (of course then it hid all walls) but when I connected the polygonside node, it does nothing.
I even now tried it exactly as you showed, still no luck. I used simple cube to mimic a 'room' to get the same result as in LW by flipping the room polygons.

What did I do wrong?

Stef, the camera clip does not work as it clips along the normal to camera so the wall is partially visible depending on the angle. It does not clip whole polygons.
