Isn’t that just the ambient occlusion setting in MSFS? Can’t that be lowered in the graphic settings page?
edit: sorry I was late to the party. I’ll have to check in sim. I was fairly sure that the effect could be reduced in the settings.
Due you post in the Maps2XPlane sub-forum, I assume you ask about the procedure that I use for my own products and business customers: I've developed my own toolset for creating and editing X-Plane Meshes. More info about my tool to edit existing X-Plane meshes are available in the development blog on my website. In short: The tool isn't publicly available until now, I'm still improving it in partnership with renowned scenery developers. Who's running a development studio and interested in a cooperation, can read here more about my mesh development- and mesh editing-services.
I believe you do in fact have an XBox Live account, as it was used in part to authenticate the installation. There might be some hints in this link that could help, while someone else more knowledgeable on XBox weighs in. Also, please check the Windows Store update area to ensure you have the latest related support apps.
Gents, this is not the thread nor even the forum for debating the merits of any sim over another. This thread is about the work-in progress Brandenburg for MFS only. Please, let's keep it to that. Further off-topic posts will be hidden from view. Thanks!
