DXX Raytracer
DXX Raytracer is a fork of the DXX Retro project for Windows. DXX Raytracer uses modern raytracing techniques to update the graphics of the beloved retro game known as Descent.
Installation
Download dxx_raytracer.zip here.
Extract the zip file to a location of your choosing, and just run descent1.exe to play! This build of the game uses the shareware assets. If you have bought the original version of Descent 1995, you can replace the descent.pig and descent.hog files with your versions to play the whole game.
IMPORTANT: Versions older than 1.1.0 will crash on NVIDIA graphics cards with drivers newer than November 2023, which has been fixed in the 1.1.0 release.

Texture compression - generating DDS textures
To create DDS textures: Download NVIDIA's https://developer.nvidia.com/gpu-accelerated-texture-compression to compress the textures. We have prepared a script for you to convert a batch of textures to the correct format and settings. You can run the python script in a command line python PNGToDDS.py \<path> with a path to a directory that contain the PNGs to generate an nvtt file. That file can then be executed with nvtt_export --batch "DXX_Raytracer_Convert_PNG_To_DDS.nvtt". That will generate DDS files for all PNG files in that directory specified in the python script that follow our naming conventions (filename_basecolor.png, filename_normal.png, filename_metallic.png, filename_roughness.png, and filename_emissive.png) and use the correct settings for each of these types. If you do not decide to use our python script, make sure that you generate DDS files with mips already in them, and emissive textures should be pre-multiplied by their alpha.
