Finally, for a few weeks, the majority of all our teams had to stop working on anything related to our future projects, and go through all the game objects, vegetation, vehicles and effects rebalance things, over and over again, to synchronize them to a shared and agreed upon albedo reference table. We are talking about thousands and thousands of such retouching, in some cases involving not only a few dozen 'numbers' defining the lights, but also major changes in the lightmaps of objects, where false shadows and lighting effects have been ' integrated вЂќfor a better look in the old lighting system. In many cases, this meant that a game object like an entire factory or a delivery yard with predefined light sources had to be reopened, adjusted, and re-exported back into a 3D tool like Maya. First of all, we had to readjust all the light sources in the world and all the vehicle lights.

SCS Software: вЂњAfter our small team implemented all the necessary code and GPU shader changes, which took many months of experimentation, we had to involve a lot more people. And that's when a large majority of our art team had to be involved for a major overhaul.

Our concrete surface can no longer be some kind of gray, and a tree cannot just be beautiful and green. The new exposure emulation system is much more sensitive and simply requires physically correct brightness albedo values. Over the many years of development, we have accumulated tens of thousands of textures, some from photographic sources in various settings, some hand painted, others through the process of procedural generation in various intelligent tools.

When a ray of light is projected onto the surface of an object, what is reflected or refracted depends not only on the properties of the incoming light, but largely on the properties of the object's surface. вЂњWe have followed this development path (editor's note: HDR lighting) until we realize that if the results were promising, we won't be able to achieve this without rebalancing ALL existing materials / textures on all objects in the game. When we started experimenting with the new technique about 18 months ago and saw the first results, there was no going back for us, we knew we wanted that in the engine.В В» If we are able to properly store the intensity values вЂ‹вЂ‹of light sources and, more importantly, perform all light / surface operations at their appropriate value ranges, we can do true high dynamic range (HDR). In the real world, the difference between the intensity of a bulb and sunlight is several orders of magnitude. color and light with much higher precision and range. вЂњIn recent years, the explosion of memory available in 3D cards, increases in computing power and the flexibility of shading languages вЂ‹вЂ‹for programming 3D card operations have paved the way for the storage and calculation of values. This is how all the values вЂ‹вЂ‹were defined, whether in a texel of a texture map (the 'skin' of a 3D object, a tree, a vehicle or a skybox), or in the encoding of the intensity of a light source (from the tail lights of a vehicle to streetlights, to the intensity of the sun), and combining all of this in the rendering step into one pixel this was again the representation in the display buffer to be displayed on the screen, with only 256 shades of each base color. It was a time when the state of the art was to represent all RGB values вЂ‹вЂ‹in the numeric range 0-255, to fit into one byte of information. SCS Software: вЂњOur 3D engine's approach to representing light and color in scenes - and in the render buffers that end up being displayed on screen - was established over a decade ago. We translate all this for you (and we cut a little long passages): And there was light ! In one blog post, the developers come to talk to us about what is really going on вЂњunder the hoodвЂќ. By far the most visible change is the new lighting system, which turned out to be the biggest graphic overhaul since the release of these 2 titles.

The changes introduced with update 1.40 for American Truck Simulator and Euro Truck Simulator 2 have been visible to the public for quite some time now, in the currently running open beta versions.
