A while back, Nvidia and Lightspeed Studios released a really interesting tool called Remix. It intercepts the rendering pipeline of older DX8 games, and injects a Vulkan renderer. This allows them to display a fully path traced and PBR rendered version of the game. Even better, the tool allows for injection of meshes and textures as well.

So... now I guess I'm remastering Bloodlines... asset by asset, hand crafted! Using a mixture of Substance Designer/Painter, Toolbag 5/ Blender, and Zbrush. No generative AI.
