Thanks! Will attempt to do that.
EDIT: I send the mails. It seems that Joerg is unavailable at the moment, so he'll reply after August 10th. At least that's what the auto-reply said, duh.
Well, time will tell. I can tell you what this is about, though. On
BeyondUnreal Forums there are three threads in total concerning the so called S3TC maps for Unreal. These are shown in the article I linked to.
Now, in the TweakPC article there seem to be several additional levels: the Graffiti Museum has been updated with a mirror (the multitexture screen) and there is a SPACE environment shown. Now I guess the author of this article might have received the maps for testing (there is a possibility) so I'd like to ask that person to share the additional levels to help complete the S3TC map pack. That's my only lead now.
