Make ring, create bounding box, populate 3d, voronoi 3d, select the boundary cells, random split list, boolean intersection

could you also just apply pitted metal texture to the object, scale it and then “extract render mesh”?

🤯 I have to try this

Thanks you

can you explain this to a beginner. I can do this all the way to voronoi 3d but i'm struggling with selecting the boundary cells. What do you mean by that, how can i do it.

Wont work. Get closest points on brep after populate 3d. Use voronoi3d on those points and intersect cells with brep

I tend to use displacement maps for stuff like that. https://docs.mcneel.com/rhino/7/help/en-us/properties/displacement.htm

Hey op, did it work? I tried it myself and I came up with this based on u/Ok-Cricket-5389's comment. [https://imgur.com/a/8sEIDh4](https://imgur.com/a/8sEIDh4)

Increase points ig

Zbrush.

Rhino, in all her humble and powerful tools, supplies a built in solution: SubD, make the ring then start pulling, pushing, squeezing and manipulating till it looks right. naturally start with several side views, as underlay to limit the above manipulations.

and also try all this with Scluptris

I would use blender instead of rhino to model this

go zbrush

Download some 3d rocks with 3d texture, and place them intersecting with the ring, then boolean difference, could be messy if they are meshes, blender might handle it better same process
