plastic foam ?

very nice Lucutus :-)

Close up rendering of the last setup.

seems to work for close ups too ;)

Very convincing! So basically it's just a mesh with proper displacement and bump maps?

[Lucutus]

in this case its four meshes of the torus with different diameters to simulate the depth.
Just like rambambulli described.
I just added a bump and displacement shader.

Lucutus, can you share a screenshot of your material setting? I don't know what I'm doing wrong but I can't reproduce it.

thanks

[Lucutus]

Maybe its the adjustment of the noise map that causes your problems.

I did interpret "edited curve"

standard noise map with a edited output curve.

differently :)

Thanks for sharing!

Hello,
Hi,
I'm looking for sponge material and found this thread. Does anyone have the textures? I'm working in C4D, but at least the textures would be useful.
Thanks

This thread is 8 years old. I would not expect any HDDs where those textures were stored to be still alive. :)
I think at least some examples here were made with procedural textures though (things like noise/voronoi cells).
