I have been trying to make a map again and now i realize that all the changes i made to my map's ground are also made to the original map (small island). "Original" small island:
Ok, what has probably happened is that you have not renamed name of the terrain in all of the info.json files, there is one that is hidden quite well. On one of my endless projects it is in this folder levels\fufsgfen_city\main\MissionGroup and line is like this : {"name":"Terrain","class":"TerrainBlock","persistentId":"4404e4bd-a371-4ccd-a9d0-03bd6528dfd0","__parent":"MissionGroup","position":[-1023.370300292969,-1049.566040039063,-272.77392578125],"terrainFile":"levels/fufsgfen_city/fufsgfen_city.ter"} It can be also levels\fufsgfen_city\main folder, open items.level.json in both folders and see which one has that line above, it starts with "name":"Terrain" Next change path and terrain file name to what you want it to be and after that copy .ter file from \levels\small island or whatever that line originally says terrain file to be in to place you changed that line to point at, don't forget to rename .ter file to be same as you named it to be on that line. After doing all that, it should fix small island, maybe It is bit of a mess really, original Torque3D works fine when you do save as, but BeamNG version of level editor is not quite working so well with save as and you need to manually go trough files and rename paths etc.
