|Overview:||Rendering Kyrat, the beautiful world of Far Cry 4, inspired the development of many new graphical features to use the power of the new generation of hardware. First, the foundations were laid down by lighting and material improvements. An anisotropic BRDF was created, high-resolution directional sky occlusion was added, and the global illumination system was extended. Next, the vegetation system was rewritten from scratch, resulting in individual leaves being modelled up close to tessellated, displaced billboards in the distance, complete with physics simulation. Finally, overall image quality was improved through the use of temporal stabilization using motion vectors, SMAA and our "flip quad" super-sampling.|
