BB-8 in blue

This is rough representation of the BB-8 droid from the Star Wars saga.
It was created as a skills testing.

The background panels as well as floor were modelled manually. BB-8 was created by arraying its circle blocks; so it consists of several parts.
It uses several materials which were assigned based on its topology.
It uses generated texture coordinates for roughness map for the Glossy and Anisotropic shaders.
Volumetrics effect from the lines on the floor was created with post-production.
