Thank you so much. We are a smal studio so it was quite a big undertaking for us.
Corona was used only in the beginning, with the old cars and the transformations, which was separate from the film itself.
The stills sums up most of the shots where corona was used.
The other shots in the end part of the commercials/trailer was done by other studios, Im not really not sure what render engine they used.
Corona is pure awesomeness:D I think the only problems we had was with the shadowcatcher taking some time to clean the noise, so I chaged to a Ao hack with abit directionality on one of the shots, and the rendertimes went down. We did have alot of noise in the dark environment where we used RoundEdges on som of the internal mechanical parts, this was fixed abit with projecting the reflection pass(which had the most noise) ontop of the geometry in max and re rendering with only motionblur. Super hack:P
We used max 2016 with corona 1.4, rendered everything at rebusfarm and compositing was done in nuke.
We were 3 guys doing the transformtions over a roughly 2 months time periode. In total it was 8 cars we had to texture and do some remodeling on.
With all the animation, camera tracking, projections, lighting, rendering and compositing time went by fast, but we are pretty happy with the end result.
I mostly do compositing work so this project was a new experience for me and the guys, we chose to use corona because of its ease of use, speed and great interactive rendering.
Looking forward to try out all the new features in 1.5, it looks amazing.
