Abstract: Systems and methods for optimizing a model file include an occlusion reduction process. The occlusion reduction process includes acts of: i) identifying one or more points on a mesh section of a model, ii) determining an occlusion value for each of the one or more points on the surface of the mesh section by performing a ray cast rendering of each of the one or more points, iii) determining whether the one or more occlusion values meet or exceed a predetermined occlusion threshold value, and iv) removing the mesh section from the model. Systems and methods for optimizing a model file may include other optimization processes, such as an instancing step, a selective decimation step, a texture reduction step, and/or a texture formatting step.
