OK, I am no Shattari or Ginsan (or insert your favorite master-builder here) but I gave it a run at the latest UI in Voxel Studio 3 just to see if it felt right. You can see a live capture here:
This build used lots of UV-mapped meshes. Well, it uses two or three different meshes many times over. This feels closer to building with props with the difference they are fully voxelized so you can copy-paste, deform, and continue to mess with them. When they intersect each other they behave like any other voxel content, you do not get hidden faces, you get only the surface. The mesh is gone after you voxelize it, which is a good thing otherwise this build would have dozens of thousands of individual props.
This was around two hours of work. I had little idea of what I was doing. You can tell I did not prepare well and I got a bit anxious to finish the bottom part so I could go to bed. However, I did like how the tools are arranged in the new UI.
I can hardly wait until this new generation of tools reaches the very talented (and patient) builders out there.
