I though I would never manage to finish that one! Sometimes you start with a simple idea but end up debugging issues for hours... Everything is modeled procedurally with lots of of "simple shapes" combined in and out. And shaded procedurally as well in Karma.
** edit ** intention was this render but ran out of time to finish so entered the still image. bonus mpg this time added on after time deadline so still a still image entry
Late entry for the Iron man... So I tried to make a simple shape medallion, and remove a complex shape as a hole, but a lot of things broke, including my brain at about 11pm. Then hacked plan B together and liked what I got.
