Update, I spent some hours more on the generator and I came up with some interesting results. I consider these to be pretty close to what I aimed but I do feel there's still room to improve. I followed this process ( https://www.youtube.com/watch?v=2oC9TOgQ3KE ) with point vops and went through different kind of noise iterations. Suggestion for improvement are welcomed! These are rendered in blender w octane, the look is a bit different from the suer polished one that I posted as reference, but the structure I followed is the same

Hey everyone, I'm a generalist newcomer, I've been lurking for some time around Houdini and lately found some time to get into it. I decided to start my learning with a classic, procedural rock generation, I've been following some nice tutorials with good results (youtube.com/watch?v=2oC9TOgQ3KE youtube.com/watch?v=-IcOKBNNfyo&list=PLNbgmFvU__fiEIv-g12l5KDiW1YAH9MRt&index=2) So I decided to do my own version of it and I wanted to recreate this kind of silicon mineral, because I find the form of the surface (and material) really fascinating. Now, I think the general setup from the turorials I followed gets me in the right direction for the shape of the rock, I can get the sharp edges and all. What I am struggling with are the smaller details, the tiny grooves that follow the direction of a face, the diversity in the surfaces the fact that some faces stay smooth while others are sharp and jagged. The tutorials I followed use vop noise layers (both vdb and geometry version) to generate details in the form, but I cannot seem to find a good combination of noises to get close to tis shape. I am even wondering if the vop approach is at fault here, and maybe I need to try something else for something like this. But I don't know what exactly. So I wanted to ask fro help and advice from the more experienced users, let me know if you have some ideas or knowledge you can share on this problem!

So nice, where can I find some tutorials/info on this kind of thing? I don't know how/what to search for this
