OTOY Forums

I was watching a Modo tutorial where the tutor set up a plane with a semi translucent /frosted material behind a product and shone a light through it to produce a nice graduated background. The sort of thing you might do for real in a photography studio.

Is it possible to do a similar thing in Octane? How would it be done?

Very likely with the specular material playing with the roughness channel for opacity
or/and the transmission and medium channels for the way light goes through the wall, but I guess without forgetting that the wall should better be thick object (e.g. a cube rather than a plane).

But being a recent user of octane It should be asked to pros ...

Is this the kind of effect you had in mind ?
It's just a quick simple setting with three lights,
one being behind a "frosted" specular material with just a turbulence noise
plugged into a gradient in the roughness channel...

Thanks guys, that is the kind of thing - I put some roughness in the spec channel and it's working nicely. I'm using it with an octane light behind so that one edge of the light is touching the diffusion and one edge is rotated away, it gives you a nice gradient fall off in reflections.

Consider also you can use the medium and transmission channels with colored gradients, and it can give you some depth and subtility in the background material...
