I like the way you solved the loading image to hide the white_plane mesh, just a point about the instructions.
Don't replace anything from the base game, TW provided other ways to do this without replacing original files:
- 'core_ui_meshes.brf' should be dropped into "..\Mount&Blade Warband\Modules\*MODULE-NAME*\Resource", as long as it keeps the same name, the game engine will take it into account and will ignore the one from the CommonRes folder,
Swyter said it here, too. The same happens with all the ones that start with 'core_', it is not necessary to add them to module.ini, as it happens with the rest of brf's if we want to replace some mesh, texture, whatever.
- 'ui.csv' should be dropped into "..\Mount&Blade Warband\Modules\*MODULE-NAME*\languages\en" in the case of using the English language.
Run your tests.
Maybe your contribution should be in: 'The Forge - Mod Development'
