2) Upload your .sco file to:
"mbwarband\Modules\Native\SceneObj"
WARNING: Make sure to replace "Native" with the correct module name your game server is running!
3) In "mbwarband\Modules\Native" (make sure you use the correct module again!)
open the file "scenes.txt" (opening/editing might need you to download the file to your own PC first, save it, edit it, save it again and upload it).
When editing the scenes.txt you need to add at the bottom something similar as:
scn_random_scene_steppe_forest random_scene_steppe_forest 1792 none none 0.000000 0.000000 240.000000 240.000000 -0.500000 0x300028000003e8fa0000034e00004b34000059be
DO NOT COPY THE ABOVE! As each map comes with different text for the scenes.txt and some do not require it. If they do, it should be posted on the forum you downloaded the map from or in the readme file which comes with the map.
4) Do not forget to set the map to start in your Control Panel --> Configuration Tab. Start your game server and your custom map is running!
In case you face issues getting your map to start please do not hesitate to contact support.
