The hidden 3D editor can only save to biedi and can`t export to sqm this cause a game crash while loading scenarios. I know the 3D Editor has many issues and it would be a shame to call it a part of a finished game. But maybe you could give all the necessary sorce code to the community and assist them in completing the 3D editor. This way the 3D editor could maybe a part of the next games of the ArmA series and add many opportunities for the player.
