As we've already mentioned, Minecraft with RTX's worlds are almost entirely path-traced with lighting and effects featuring incredible levels of detail for the very best image quality that is possible. Here's a list of all the main effects, in case you are curious or just would like to know more about the technology behind Minecraft using the RTX engine. https://gservers.org/minecraft-servers/

Global Illumination

Games are typically lit by pre-computed lightmaps, Image-Based Lighting Probes, Spherical Harmonics, and Reflective Shadow Maps and artist-placed lighting to help force illumination when the above methods fail. Although the results look amazing but the methods employed have a few flaws, the biggest of which being that dynamic lighting fails to reflect or illuminate beyond the region that the light is hitting.

Imagine a dark room with bright sunlight shining through windows. Traditional methods illuminate anything that is directly illuminated by light. However, the illuminated areas are not reflective and, therefore, do not light the game elements around them.

With path tracing, we can accurately model the dynamic indirect diffuse lighting reflected by one or more indirect bounces off surfaces in the scene and have it interact and play with other ray-traced effects. Imagine, for instance, sunlight beaming into a castle through multicolored stained-glass windows and refracting to illuminate every corner of the room reflecting off the glossy marble floor, and increasing the surrounding detail, creating new shadows that harden contact to be cast by objects.
