To achieve the typical PBR look from an artistic point of view it also means to that it is necessary to add indirect lighting.ĭoom 3 and even Doom 3 BFG had no indirect lighting.ĭoom 3 BFG is a big game. Baked Global Illumination using Irradiance Volumes and Image Based Lighting The Ambient Occlusion will be mixed with the Screen Space Ambient Occlusion and will only affect indirect lighting contributed by the environment probes. Old school specularmaps also go through a GGX pipeline but the roughness is estimated from the glossmap. overrides for old materials and if it finds those it will render them using a better PBR path.

Specialized rendering paths for skin, clothes and vegetation will be in future releases. The PBR implementation is restricted to standard PBR using the Roughness/Metallic workflow for now. With RBDOOM-3-BFG modders can work with modern tools and expect that their content looks as expected. PBR became the standard material authoring since 2014. RBDOOM-3-BFG only supports the standard PBR Roughness/Metallic workflow.Īdding PBR is a requirement to make the new content look the same in RBDOOM-3-BFG as in Blender 2.9x with Cycles or Eevee and Substance Designer. PBR allows artists to create textures that are based on real world measured color values and they look more or less the same in any renderer that follows the PBR guidelines and formulars. However I also want to support the modding scene to allow them to create brand new PBR materials made with Substance Designer/Painter or other modern tools so multiple rendering paths have been implemented. The light rigs aren't made for PBR but it is possible to achieve good PBR lighting even with the old content by tweaking the light formulars with a few good magic constants. Implementing Physically Based Rendering (PBR) in Doom 3 is a challenge and comes with a few compromises because the Doom 3 content was designed to work with the hardware constraints in 2004 and that even meant to run on a Geforce 3.
