In this film, shot on Alexa and then motiontracked for 3D cameras we had a vision of creating photoreal grass and flowers well integraded at our environment. The lighting is made mostly by on set HDRI, but to get shadow of the cars etc we also made perfect sized 3d modelled cars, object tracked in motion, to use for shadow passes when rendering the grass.
We planned to get a moving camera in every shot for more realism. Since we knew the exact size of the cars, this also helped us to get a perfect scaled track. All plants and grass were made in full 3D. In addition, all of the growing flowers we built from scratch in order to have full control over the textures and the details in the animation.
