[Development] Dagor Engine 5.0: light and shadows: Global Illumination, contact shadows, shadows on effects
Several lighting and shading algorithms are used when rendering each frame in War Thunder. In the updated Dagor Engine 5.0 render, we are improving the lighting model with Realtime Global Illumination. Global Illumination is the common term for lighting algorithms, this includes not only direct illumination, but also reflected and scattered light from surfaces and area lights (such as sky and clouds). Our game will have shadows that objects cast from ambient illumination and the sky making the visuals more volumetric and detailed in shadows. Global Illumination will also introduce light reflected from other objects and the environment. All of it will be implemented in real time for large scale locations (the average WT location is 32x32 km) for destructible and dynamic objects Like other upgrades to the game’s visuals, Global Illumination will be available as an option in the graphic settings menu and will be enabled by default for high graphical settings. Global Illumination - is a complex mix of algorithms, a very difficult and high-technology task. It’s enough to say that at the moment there is no game or game engine that has a fully fledged dynamic GI for large-scale locations. Algorithms where the objects are supposed to be static or require preliminary calculations won’t work in War Thunder: dozens of large-scale location will require excessive memory and hard drive space while destructible environment affects the whole geometry very significantly. That is why some of algorithms and improvements will, perhaps, become available after switching on some personal settings after update 1.77 is released. Meanwhile, a general list of changes is already available.
See the difference in shadow rendering and visual perception of the volume with the new Dagor Engine 5.0 shadowing algorithm.
Effects are often separate from the rest of the photorealistic rendering, as most effects are simplified versions of much more complex processes, like smoke and fire. That’s why the effects render is usually a separate process. In the Dagor Engine 5.0, we have calculated the shading of effects by environmental objects, such as exhaust fumes or clouds of smoke from a burning tank, making them look more three-dimensional and natural in the final image:
In our new Dagor Engine 5.0 graphics engine, to be introduced in War Thunder 1.77, we’re presenting an algorithm for creating contact shadows, which make the image more realistic and give depth to maps. Technically, the algorithm for drawing contact shadows relies in fact, on rendering each frame, every pixel in the image undergoes ray tracing for a short distance toward the source of light. The tracing takes place through other objects already drawn on the screen. If an obstacle appears in the ray’s path, an additional shadow is created. Changes in the grass will be particularly noticeable: grass in the game could previously take shading from other objects but couldn’t give off shadows itself. The technology of contact shadows not only allows grass to give off its own shadow on the ground, but also give shade to other grass. As a result, grassy meadows and fields will now look deeper and more realistic, both up close and at distance. Apart from grass, the technology of contact shadows provides a means to create great depth in all objects far away from the player. For example, window frames, rivets on vehicles, and other objects receive visually more correct sub pixel shading, in contrast to classic shading methods in which shadows at great distances are drawn only on large objects.

Today’s edition of our devblog will discuss how the updated Dagor Engine 5.0 render will add volume to the War Thunder world. It’s all about light and shade!

War Thunder is a free-to-play, cross-platform MMO combat game for Windows, Linux, Mac and PlayStation®4 dedicated to military vehicles used in and around World War II and the Korean War. In War Thunder, you can take part in major battles on land, in the air, and at sea, fighting with real players from all over the world in a continuously developing environment.
War Thunder already offers a highly detailed experience in military aviation and ground forces combat, giving players access to a Guinness World Record breaking number of aircraft, as well as an abundance of tanks and other combat vehicles - and the number is constantly rising.
You can feel the unmatched intensity of aerial dogfights in a fighter, the decisive power of commanding a heavy strategic bomber or the heat of battle in a ground attacker, delivering precision strikes against your enemies. Alternatively, you can join the spearhead of armoured vehicles, fighting for dominance over the battlefield on the ground: Man a heavy tank with impressive armour and firepower, use the maneuverability of a medium or light tank to your advantage, or support your team by screening the skies with your anti aircraft vehicle - the choice is yours!
In the future, the game will also allow players to ‘set sail’ by commanding a variety of warships in the fight over the control of the world’s oceans, giving the game a truly epic scale.
Master your vehicles through both upgrades and personal experience in an environment that is constantly expanding and rewarding the personal skill of the player. Organise your efforts in one of the countless player squadrons and become an ace pilot or tanker - or both! Our thriving and welcoming community of millions of players is also actively participating in the game’s ongoing development, offering custom content through War Thunder Live, such as skins, missions and even vehicles.
War Thunder has something for everyone. Play cooperative games with your friends on Windows PC, Linux, Mac or PlayStation 4 against AI, or squad up for a PvP battle in a difficulty setting matching your play style, ranging from Arcade to Simulator using Mouse and Keyboard, Gamepad or Joystick.
