Thanks to NVIDIA RTX Remix tools, tech enthusiasts can integrate modern technologies into their favorite projects and significantly improve their graphics. Recently, Night1099 decided to revisit a stealth classic — updating Thief Gold.
Thanks to his modification, Thief Gold will feature path tracing. Night1099 spoke about the approach to implementing path tracing (it didn't work correctly "out of the box"):
The d3d9.dll proxy restores the game world geometry, mirrors the engine's lighting table to light sources for path tracing in Remix, and renders the HUD as an orthographic UI (interface) — thanks to this, Remix can correctly calculate path tracing in the scene. World geometry is transmitted as whole polygons with a stable hash from the worldrep array (world cells), with textures from the engine's bitmaps.
This project inspired another modder, jrubimf, who published an example of Thief Gold VR gameplay:
Thief RTX gave me the opportunity to implement this. In general: native OpenXR, separate view and projection for each eye, 6 degrees of freedom (6DOF). I am currently fixing weapons — yes, with gesture support. Then the interface (it will most likely have to be partially redone for VR).
The "thief-gold-rtx-remix" project is publicly available on GitHub in Night1099's repository. The VR modification files have not yet been presented — jrubimf continues to work.
