Porous material I tried to model a porous material which contain empty spheres or complex shapes, modeling it into a cube.

I found this video as an example, but the procedure was made by Cinema 4D with an add plugin. https://www.youtube.com/watch?v=mcRlTK0TUBg
Is there a technique to use procedural textures and volumetric effects to these porous texture, or if there's a script to do!
You could use 3d dimensional procedural textures for volumetric rendering:
With a node setup like:
The scale of the voronoi texture controls the size of the bubbles. You could also try noise or musgrave texture with different settings.
For more details I reduced the step size in the volumnetric render settings:
1- Using a particle system and a sphere mesh as the object fill
a box the more variety in sizes the better, the box will need to be larger than your final "block"
2- Convert the particle spheres to real geometry and join them together into one mesh.
follow this tutorial: https://www.youtube.com/watch?v=1gM8yEMFMjg
Then using modifiers ,
3- Remesh using voxels.
4- Decimate to break up spherical obvious shape.
5- Boolean intersection the sphere mass with a box with a box with actual dimensions you want .
6- An other voxel remesh (finer resolution)to eliminate boolean artefacts.
As to make volumetric porousity on volume level for your bony object ,I found a useful blog with beautiful open source downloadable plugin AtomBlend, developed in Sydney by Vavara Efremova under the supervision of Anna Ceguerra, Simon Ringer and Peter Felfer. It works for Nano particles material research . so can handle enormous number of vertices for visualisation , render and analysis .You can load your object vertics data and make Atomic view and switch halo material (circles as atoms) to Vertex duplication (spheres as atoms) by switching On Vertex Duplication in the object tab.
