Even where dynamic shadows are enabled, there is an edge beyond which the shadow is no longer calculated.Our dynamic shadows are not enabled on all devices, so we have reasonable static shadows even without shadowmaps.We can use component-by-component information separately to modify direct and indirect illumination, leaving the PBR calculation physical.There were 4 main arguments in favor of this approach: In the first texture channel, we added shadows from a direct light source, and in the second channel, we added Ambient Occlusion. The solution we found was to continue to bake the light, but for PBR, we now put non-finally calculated light into the lightmaps. Since no dynamic light sources were applied to houses – regardless of the angle of view, the lighting looked the same from any side (but still looked pretty decent, considering its limitations).īut how to make it look even better? Ideally, we wanted to be able to include lighting components that add realism, like indirect lighting and self-shadowing objects in hollows, where it is more difficult for light to reach. These textures are called lightmaps, and the process for calculating them is called Lightmap Baking. Before 9.0, these objects were not dynamically lit - the light calculation was made in advance and saved in textures, which were added to the game resources. This includes houses, stones, benches, and fences – everything which adds that lived-in feel to the map. First of all, we had to decide how the lighting would interact with static objects.
