DOOM 3 BFG EDITION UPDATE

I also needed to add environment probes for each room so PBR materials can actually reflect the environment. I needed a good automatic solution that fixes the pitch black areas without destroying the original look and feel of the game. Each room can have up to 50 shadow casting lights and most of them are point lights. Doom 3, Resurrection of Evil and Lost Missions sum up to 47 big single player levels with an average of ~60 - 110 BSP portal areas or let's call them rooms / floors. 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.

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.

DOOM 3 BFG EDITION UPDATE

Update texture compression based on Basis Universal GPU Texture and Texture Video Compression Codec.

Explore Screen Space Global Illumination with Christoph Schieds' A-SVGF realtime denoising because A-SVGF works really well in Q2RTX.

Scrap expensive multipass forward shading with a faster forward+ solution.

Optional RmlUI support as an alternative to Flash.

DX12/Vulkan renderer backend using the NVIDIA Rendering Hardware Interface by Stephen Pridham which will lead the path to advanced Ray Tracing techniques.

Improve MD5 files with a new Version 11 that allows to store normals for better control of smoothing groups.
