(I dont use Blender very regularly and am currently quite rusty)
I've been seeing art like this a lot lately (maybe some algorithm has discovered I like such things) and have been wondering how people do this. I understand that the material in such artworks are going to be tricky: refractive-glass, i think? But I was just wondering how are such sculptures modelled? Is this a flat plane with some bumps? Is it a completely different shape clicked up-close that we cant see?
For the below photos, the artist listed Cinema 4D, Octane and Photoshop but I'm sure Blender can achieve this too.
