We decided to make one topic for Madeira mesh issues to avoid a lot of overlapping topics. Start by reading with the developer here explains, it will solve almost all of the issues.
Please do NOT discuss any other issues but mesh conflicts here!
Ok, I've done some post regardin Madeira troubleshooting for many products. Some of them are similar to those experienced in the previous product, common thing is that they're mostly caused by 3-rd party addons.
If having mesh/coastline issues please check:
1) If the default files were excluded correctly
In FSX/P3D main/scenery/0502/scenery check if you have those files disabled/removed
If not move them or change
