I would like to render a sponge mushy thing like the one featured in this picture

https://home.otoy.com/otoy-unveils-octa ... -renderer/

But how? I can't seem to find the settings?

Unfortunately there wont be a setting for "render a sponge, make a car, make a awesome looking interior".
To me it looks like a distorted mesh, try to use a noise as displacement.

cheers

This picture was made when Octane team was first experimenting volume rendering.
Basically they were generating a surface from a procedural 3D texture, but since then they abandoned this technique. (too slow I think)
Now volume density is only rendered from OpenVDB grid but you can't have a feeling of solid surface with this,
so to approach the same result you should use a mesher to extract a polygon surface from your volume density.
I don't know if there is mesher for this in C4d, but there is a very quick mesher in the openvdb toolkit.
(you can do this for sure in Houdini or Maya with openVDB nodes).

Thanks, I see I would probably need to go the meshing route.

Has anyone tried this in C4D? Sounds like a cool technique.

Might want to try out Code Vonc's Procedurale plugin, I'm not sure if it's OpenVDB under the hood, but you end up with geometry (can be a lot if it's high detail) and that can be sent to Octane just like normal. It gives similar results to those octane Volume Primitives.
