started to work on something different for a change a couple of weeks ago, no cel rendered stuff this time... had a lot of fun building the materials. was a bit tricky to get the post DOF right in conjunction with hair, but fortunately i found a solution that works perfectly. all physical renderer, no GI. car model by vector.
