This contains all original RBR stages upscaled 4x using Gigapixel AI. Results are not perfect but they look quite good if you don't look too closely. This is only textures so models with low polygons still retain that ps2 look. Essentially trees just being in - or + shaped. This could use some manual retouching/fixing for a really good result, but I will personally not be doing that.
If you are running the game at lower resolutions this is probably not worth installing but it should be quite nice for 4k res people and VR people.

Conversion info:
When converting DXT3 format was updated to DXT5 format. All textures have mipmaps like they are supposed to.
DXT1->DXT1
DXT5->DXT5
DXT3 converted to DXT5
Known problems:
Alpha doesn't look quite correct for some things. And objects have a black outline instead of a soft edge with Alpha like in the originals.
Archive contents:
Maps are split into four parts:
- Part 1: Arctic + British
- Part 2: Australia + France
- Part 3: Hokkaido + USA
- Part 4: Cloud + Sky textures + Rally school + extra stages(like Rally Yard)
Upscaling process:
I used this script to help with the process: https://github.com/Tomas-B5/Texture-Upscale-Helper/blob/main/UpscaleHelper.py
- Convert textures to .png.
- Flatten the file structure.
- Add all files from the base directory to your upscaler, And upscale the textures. I used Gigapixel AI. Saved results without filename modifications into a different folder.
- Restored file structure so that textures go back into their own folder.
- Converted PNG to DDS.
