Abstract
Approaches presented herein provide for the generation of visual content, including different types of content representations from different sources, rendered to include consistent scene illumination for the various representations. A first render pass can produce a first image including only proxies of implicit representations (e.g., NeRF objects) under scene illumination. A second render pass can produce a second image that includes a representation of the explicit scene objects, as well as the proxies of the implicit representations, under the scene illumination, which produces secondary lighting effects. The first and second images are compared to determine irradiance ratio data for the various pixel locations. A third render pass can produce a third image that includes the implicit representations, which can have relighting performed according to the irradiance ratio data to include the secondary lighting effects. The implicit and explicit objects can then be composited to produce an image with consistent scene illumination.
