We have already posted the making of the Ford Explorer advertising print campaign in January. This time we would like to show you how we made the amazing 360 degree views of the car that our team in New York and Berlin have produced nearly entirely in CG. Yes, both the car and the pebble floor! The sky and surrounding nature were shot by photographer David Westphal.
One challenge faced by our team was the technical restriction given by the Ford web team. The animation could only be a max of 72 frames (and the current Ford website will only show 36 of them). This also explains why the final videos are not a very smooth animation.
But for our CG artist Richard Jenkinson the main challenges with this project were the size of the area of floor that needed to be rendered, and the level of detail required. The geometry of the pebbles had to be managed in an efficient way to achieve a realistic render-time. The camera gets very close to the floor at one point in the move, so the detail needed to be there, but not everywhere, as this would have been way too much geometry to render effectively.
In the end we decided to use displacement maps on a low-poly floor. Richard then used normal-mapping to add fine detail to the geometry. Below is how we did it.
Firstly, Richard studied reference photos from the actual shoot, specifically the scale of the pebbles, and how the tracks are formed in them.
The amount of polygons required to render in CG the whole floor were far too many to have on one plane. So Rich took 4 overlapping planes in Zbrush, to test whether the repeating texture was going to work as a displacement.
He then sculpted the tracks into the floor in Zbrush. Below is an early test image of the scene with a simple lighting set up made to check the scale of everything relative to the car. It was also used to see if there was enough detail at the lowest point of the camera’s move.
For this reason we scattered more pebbles geometry across the floor.
Below is the final pebble floor with reflection maps added, and the correct background and HDRI lighting situation ready to be rendered, and composited with the car which was made by our New York team.
Below are the final 360 degree views of the Ford Explorer in Ruby Red. The whole range was shown on the Ford website.
