subsurface scattering shader

[Garrick]

Hello,

While waiting for an email with my license, I would like to know if a subsurface scattering shader is being planned in future releases and will normal maps be implemented?

Thanks

Hmm there is normal maps already implemented, as for the SSS I think that will be in Octane 2.0 as Radiance pointed many times, there was a transmittance that imitates SSS but was removed due some problems in new beta 2.1.. I hope that will be there for beta 2.2 as new material type... it was quite usefull.

Hi,

I have not received any machine ID code from you...
did you get my email with the download instructions ?
It was sent 6 hours ago to your gqprototypes email adres.

PS: subsurface scattering is scheduled for the v2.0 release in the near future.

transmittance was not removed in beta 2.1, it's just not hooked up by default.
make a diffuse material node, and connect a texture or rgb or float node to it's transmission channel to use it.

Ha I miss that thank you...

Hey Thanks for the help,

I am up and running and Octane is very impressive.

A few more questions how do I smooth my mesh surface and is there a tutorial on the daylight or night feature for an interior scene,

Also when I import a mesh it isn’t centered, how can I change this?

can you explain how that transmission node is supposed to work? I can't see any difference when plugging a color into it.

You should center your mesh upon exporting, we have plans to add features to import them centered for beta3,
but for the time being you should make sure you're mesh is located at the origin (eg center) before exporting.

regarding smoothing, you enable the smooth option on a material, and you must make sure you're model is propperly split upon exporting or you export with smoothgroups and enable this option in octane's OBJ import preferences panel.

there are no tutorials for daylighting, just play with it until you have something suitable.
however, with 2.1 and previous versions we recommend not to put glass in your windows as these versions don't yet support sunlight through glass.

you create a diffuse material node, connect it to the socket in question (the material socket on your meshnode),
and connect a rgb/float/texture node to it and make it a bright colour, then reduce the diffuse colour and you will see the object become more and more translucent when you decrease the diffuse reflection colour.

Like this? I still can't see any effect of that node so I must be doing this wrong or it's just not working on my computer as it should. Also I don't see a reflection property in the diffuse material so perhaps i'm misunderstanding your terminology...
