How to make cloud material?

[ior]

Iv tried everything but I cannot reproduce this material:

cloud

This images were taken from this thread: http://www.indigorenderer.com/forum/vie ... 8&start=17, posted by OnoSendai.

As I said in this threads:

When specular SSS material is outside light mesh, you have to use MLT and it takes a lot of time to render.

But it doesn't seem to be the case with those images.

Seems that it only works with ISL that defines SSS values for positions inside larger mesh object.
But I don't know ISL and didn't find a manual to learn, is there any reference for ISL?


It doesn't work with objects? It is not the same to have a sphere defined by a mesh, or a sphere defined by ISL inside an object?

Conclusion: you cannot yet make cloud or smoke material from a mesh and a simple specular material?

check this thread for some useful code: http://www.indigorenderer.com/forum/vie ... f=1&t=9629

Your examples are taken from some experiments in Indigo that enhance rendertime for such situations a lot.
There is no build released with this enhancements atm!

ISL is needed because of the 3D character of these procedural noise used.
Basic ISL functions like noise should be integrated into the exporters like simple to use shaders with some parameters to tweak (like in Cindigo already done)

Hi Zom-B.

I had run across that thread some time ago, I will investigate.

So no luck in making cloud material for now in indigo even with ISL?
Hope will be possible soon if I am correct..
