I would like to know how you smooth polygons in the map maker?? It does not say how 2 in the Help thing. And what does the command "Fix Texture" really do??

"- Added smooth polygon edges"
do you mean this? that's an option you have to enable by opening the file "config.exe" in your Soldat directory, clicking on the "Performance" tab and checking "Render smooth polygons".

In the mapmaker you can "stretch" the texture (the texture is the graphic a polygon consists of) so you can make a sort of 3D effect / flair / whatever.
But if you want the texture to be "normal" again, then you press "Fix Texture"

oh, k thx b00stA, that helps a lot.
