It's ya boy, back at it again with the wacky cubes. This was my first foray into using metaballs in Blender, and it was super fun making blobs instead of shards for once!
Between you and me, this is actually a composite of 2 renders - The first being metaballs interacting with a rounded cube that left harsh transitions, and the second being a rounded cube made via subdivision with gently swooping edges. You can see elements of both if you know where to look!
A short speed-model of the process!
