I don't this is a filter, but a modding tool/process that allows the modder to create textures using AI, adding PBR properties to them, and then adding Raytracing effects to them. It also gives them complete freedom to also change the scene up by adding additional items that were not inherently in the scene. They have, I feel, full control on the textures and lighting conditions they want to add to the scene. Only difference is that now they have much more creative freedom and capability to add modern features to a very old game. Main issue I am seeing, and others have pointed out, is that since this currently only works on Directx 8 and 9 games, this pipeline, as far as my understanding, will only work on the very original skyrim, and not the HD remaster.
