@Hexenlord, thank you !
Progress update :
Collected hd textures for around 37 maps or episodes and 10 from Tronyn’s maps. Am now working through Qazzaq’s extensive posts with links.
Created a QuakeOne user account to ask Talisa for the textures of the posts with broken links, but somehow im not able to post messages yet, i have contacted the webmaster, am awaiting response.
The aim is to preserve only the hd textures for the custom maps. As they are prone to getting lost into oblivion i have noticed.
Please feel free to add any if you have some stashed away on your hard drive
