Mesh relaxation with more control over mesh topology


I would need some advice for achieving Vault structures with a little more control over the mesh topology. I know it has something to do with the valence of the starting mesh as well, but are there possibilities to use for example lower rest lengths or higher loads in areas that should have a light crease?
I would like to achieve similar results than in this examples:

[Cohesive Construction: Spider Vaults]

[Only Compression Vault - Grasshopper]

I know about RhinoVault and already have tested it, but unfortunately, it’s far from stable on my PC so I would like to try it in kangaroo.

Any advice would be much appreciated!

Thanks in advance!
