i wanted to try out the editor on my new pc i built. and so far it seem alot stable then before. i followed the tsw4 pc editor beta video and imported the srtm terrain map in my world. it neat and i think for terrain goes i have to use srtm because i can't fine lidar data for area of BC. here some pics. it field bc area. i guess for loading terrain map it one tile at time.
i have seen this bug for tile in the editor. i started a new map and my start point was Revelstoke station. i imported the srtm terrain around the area but when i try to flatten the area for track it wouldn't work. also i tryed to lay track in that area and it didn't work. so i move down few tiles and i can flatten the terrain and also lay track in that area. maybe there some tiles that won't work.
