Thanks for replying! Had installed two xLODGens for some reason and MO was set to use the wrong one. Moved game outside program files as well. The cells I've edited landscape in are mainly 31,8 and 32, 8 and 32,7. Imgur: The magic of the Internet If use 32,8 for the specific chunk, it outputs a btr file. Worked fine ingame as well. If use 31, 8 or 32,7 it doesn't output a btr. Do you know what the cause might be? Tried different dimension 4, 8 etc. This one worked. (32,8) xLodgen worked - Pastebin.com This is what it looks like with no output. xLodgen no output - Pastebin.com
