This is with the texmem branch on R100 with the texture combine one-liner, but without cube map exported (althought the texmem branch seems to have at least the beginning of cube map support, right?): ftp://ftp.retinalburn.net/pub/ut2k3/Shot0.bmp ftp://ftp.retinalburn.net/pub/ut2k3/Shot1.bmp I don't think this is "The way it's meant to be played(TM)" :) At any rate, I think you can see from the second shot what I mean about the vertices looking wrong. -- Leif Delgass http://www.retinalburn.net --- This SF.net email is sponsored by: Scholarships for Techies!
