Meet the hare:
Influenced by the enthusiasm of some blenderartists fellows here: MagicaCSG ─ Signed Distance Fields editor by the MagicaVoxel dev 🧊 , I have decided to experiment with MagicaCSG. The idea of sculpting using SDF and thus without worrying about topology and meshes sounds too much like fun. And I’ll tell it to you: it was and I can’t wait to do more 
Here is a screen out of MagicaCSG:
Not bad for a first tentative, I think! I’ve then exported the mesh and imported it in Blender. I’ve remeshed it using Quad Remesher, and then I have refined and smoothed a few details here and there, and of course added a pair of eyes.
Love this tool and I will definitely use it more.
And so the second robot is replaced by another tiny creature!
