OSL Physically correct atmosphere shader

[jordibares]

I am keen in having a physically correct atmospheric shader and I found the famous Nishita 1993 paper on GitHub as an OSL volume shader.

Could someone point me on how to install such a shader in Arnold 4.2?
Is there any off-the-shelf version?
Any examples?

Thanks

Hi Jordi!

OSL is supported in Arnold from version 5. You can install .osl shaders as you would install any 3rd party shader, see: https://support.solidangle.com/display/A5AFHUG/Third+Party+Shaders

I also wanted to use the OSL shader you point out, I installed it perfectly and can put it in the hypershade..., but I don't know where to connect it in order to use it.

Any ideas?
