"Those are all Quake 2 textures with a bit of messing about to fit the theme - since doing this I've figured out how Quake 2 RTX materials work and modded it to load higher resolution models in maps so could improve on this a lot. There are a few free photorealistic texture packs out there that include stuff like that but would need some adjustment (roughness/specular, normal and metal/chrome maps) to make them materials in Quake 2 RTX." -Rroff

"Howdi folks! Haven't been here for a while. Previously known as Dr_CORN, the name kind of started getting old after about 10 years and started looking for a weirder name to use! I've been creating a Q2 conversion planned to grab ID's attention for Quake Live. It's still far from being complete, and probably won't be completed until late this year if not next year. Since you guys are all about Q2 it would be interesting to see the responses/ideas that I might be able to get from you. Here's some screenshots of how things look at present." -themuffinman
