volume fog in 1.11

[p3taoctane]

Will the sphere on the camera act as a lens and distort the view... where as Face's box would be a plane?.... or am I missiing something about the fog material that will negate that effect?

If the IOR is 1, there won't be any refraction.

yes, just make a sphere with inverted normals with a placement node with camera coordinates, with the same scattering material of the volume bounding box.

the inverted sphere is a big trick, thanks
a little quick test with dl-ao, dl-diffuse, pt and pmc at 16000 samples for about 16', 25', 28', 35':

That looks great
So do you have your whole scene inside an inverted normals sphere with daylight ?

I'm trying to dupe it and having issues

Thanks

hi peter,
i have open an old scene with daylight in octane, then i have loaded a cube that surround all the scene and an inverted sphere of about 100cm. i have connected all the meshes to a geometry group node, i have copy and paste the camera coordinate to a placement node connected to the sphere mesh, and connected the cube and the sphere with the karba fog material

That should work with any light sources.
Make sure you camera is outside of fog volume.

Hi Karba, can I have this scene please, i tried many times in 3dsmax but cant get liek your result
i still confused to place the camera and sphere in the best position

I also would like to see how you did the tree one in Max Karba

Many thanks

Beppe,
the fog experiments have a really strong mood. I like

thanks Nando, you know, here near Milano there is always a lot of fog
i love the new fog but the only think that i miss is the ability to add some noise like before, it would be perfect

Can someone please post an example file so I can see about it?
I am not used to scattering mats
Thank you
