The conquest
Integration of two 3D models in a real image. The characters are modeled in 3D Max software. For project light across the scene and the characters reflect light and their surroundings, we used a hdri the venue of the composition, in addition to the image where the characters are.
These two elements have been put in a environment / background switcher parameters to lead to enlightenment. Then copied the hdri to light touch and to get the shadows on the ground used a matte / shadow / reflection parameters containing the above elements.
