In deferred rendering, screen objects always receive shadows, which means trees received self-shadow artifacts while rotating. Fixed shadows look better overall, but results in any asymmetry becoming disconnected from cutout when seen from the wrong angle. These are just 2D cutouts rotating to face camera, so their shadow either twists and turns with billboard or stays fixed in place. Projecting shadows from 2D billboards comes with downsides. With all the large changes now settling down, we could start refining a few things. We helped several mod authors overcome compatibility issues so their mod works with 0.13 and beyond. The game received an extensible “Effect Settings” UI to configure postprocessing and other effects at runtime. Our new shaders were extended to support more PBR capabilities. Thanks to community feedback, we were able to address several issues created by initial 0.13 preview release. Almost every part of the game involved with drawing something to screen was inspected and tuned up if tuning was needed.

Along the way, we fixed many small problems with loose texture mods and reviewed lighting. To quickly recap, this review set out to resolve problem of specular “shine” from Unity’s default Standard shader, switch to more accurate and flexible linear lighting space, and upgrade postprocessing stack to PPv2. Preview release 0.13.3 is now available on Releases page. In this third and final instalment, Daggerfall Unity’s rendering review wraps up by fixing more bugs and giving Retro Mode some overdue love.
