Hi ALex, Been to Stadia website created the necessary credential, obtained an API key, downloaded the StadiaStamen terrain zip file. Then extracted the zip to produce a folder of same name, which I then put in my Utilities folder alongside LNM folder, under the Name "LNM MapThemes".
I deleted any reference to Stadia Stamen and Stamen in LNM Data/Maps/Earth Directory.
After that, I pointed to that auxilliary themes folder I had created, and in the LNM Directory "Tools/options/Cache and File/", with the button "Select Themes Directory", I selected that Auxilliary folder.
After a restart of LNM, I went to LNM "Tools/Map display Keys" doubled clicked the keyspace alongside Stadia API key and entered the key given in Stadia website, and again restarted LNM.
Now, I do see in LNM "View/Them/" the theme "Stadia Stamen Terrain*", when I select that map theme, I still see the Stamen map with warning tiles. Am I missing something, or has the new theme not been fully inplemented (until 31st October)? Yes and I did read the LNM manual on the subject, maybe I missed something?
