□ The use of a per pixel material map allowed the team to scale the variance back into the expected range for water, effectively fixing the specular aliasing issue.□ By generating a screen space normal map without DDX DY using position from depth, the game ensures a realistic water surface experience for players in the first-person perspective.□ The process of water rendering involves multiple passes, including writing out the total pixel count and iterating through a list to increase the indirect draw arguments buffer.□ The water rendering in Far Cry 5 uses a fractional Brownian motion with nine iterations per pixel, adding more frequency as the UV scale doubles, resulting in a realistic and detailed water surface.□ Storing various data in textures, such as shader features and material structure buffer index, enables more efficient and detailed rendering of water in the game. ![]() ![]() □ To achieve realistic water rendering, the game employs a combination of flat water and height map water, with different rendering techniques for near and far water bodies.□ The screen space tessellation algorithm in Far Cry 5 allows artists to create detailed meshes using simple parameters like amplitude and roughness.□ The water rendering in Far Cry 5 includes features such as displacement, fading in the distance, foam generation based on depth and width, and procedural waterfalls.□ The Far Cry 5 engine uses a procedural generation route for water rendering, allowing artists to easily create lakes and rivers with just a few clicks.□ Far Cry 5's water rendering system underwent significant improvements, including fully PBR water with flow maps, reflections, and refraction, to achieve a more realistic and visually appealing result.
