(Sorry about the choppiness, difficult to get size down on a GIF.)
This is an iconic logo from the 80s that I wanted to see what it looked like in 3D which I don’t think has been done before, and I went totally overboard with it…
First, I modeled it in nurbs in Rhino.
Then I used the texture painting in Procreate to figure out the back.
Finally I used lots of procedural materials with waves, noise and gradients to color it.
The only bitmap texture is the displacement of the blue graphics which I couldn’t figure out how to achieve smoothly in any other way than to take the UV unwrap into Affinity Photo and blur it and feed that into a displace modifier.
It was rendered in Eevee Next and light linking was used for the reflections in the eyes.
Nice work!
