So Rich Sedman wrote an answer / tutorial on how to make a random / organic scaffolding structure using procedural volumtetric materials. He essentially defines an isosurface in math nodes and uses shaders to render them. I would like to take that surface and use it as a mesh, but I cant figure out how.

Does anyone know of a way to turn a volumetric material into a mesh?

Perhaps convert it into a point cloud and then use marching cubes or use metaballs? Can voxel remesher be used on volumetric material?

People have seem to been doing similar stuff, I cant figure out how, but perhaps volumetric material is the wrong way to start:




How to create a mesh from metaballs which will always work with a Boolean modifier?

    $\begingroup$ I'm afraid you can't do that with Blender. However, you can try another approach like building the mesh with Sverchok/Animation Node (like OP did in your link) or the Tissue add-on. $\endgroup$ – thibsert Sep 29 '20 at 11:51
  • $\begingroup$ Ok I see, maybe I should adapt my question to how to make an isosurface mesh, regardless of the method? $\endgroup$ – Leo Sep 29 '20 at 11:57
  • $\begingroup$ Using XYZ math surface from extra objects addon? Parametric, will depend on what you want to do. In particular there is no random in it, afaik $\endgroup$ – lemon Sep 29 '20 at 12:25

    $\begingroup$ You should first explore parametric modelling with simple equations (create a cube, create a sphere, create a pyramid...) and work your way up to more complicated things, otherwise you won't understand everything and you will have trouble debugging or expanding your tool $\endgroup$ – Gorgious Sep 29 '20 at 14:20
  • $\begingroup$ I agree, I dont understand the basics (within blender at least) yet. Will go this route but will take a few weeks probably with limited time. $\endgroup$ – Leo Sep 29 '20 at 14:27
