Hi
werkkzeug3 "make demo" function seems to be broken. But as you may know, a werkkzeug3 demo exported to .kx (in werkkzeug3 File->Export) can be played with an external player (like fr-074 demo)
You can find some werkkzeug demo examples in .k format that can be exported to .kx (like debris_9241.k) in the "werkkzeug3\data" folder in the farbraush publied release of their source code as well as the werkkzeug3 player named intro.exe (you just need to rename your .kx file to fr-074.kx to play it).
So i modify slighty intro.exe to load a file named wz3dat.kx which is more sexy
wz3player.rar
