SSS on open mesh

[Mikla]

Hi,

Just a quick question, is it possible to have absorbtion or scattering medium on open meshes such as planes, landscape objects, sea etc?

Thanks.

With surfaces without thickness, like leaves and so on, you can use the Transmission channel in Diffuse/Universal materials to simulate sss:

Whit sea, the things are slightly different, since the ray doesn't change IOR until hits another surface, you can use a simple plane without thickness to simulate the sea/water with a Specular material, and use both Absorption or Scattering nodes in the Medium pin.
