After unpacking this one (it's too old for the Mod Manager to handle), you need to rename the files in the main directory so that all of them have underscores instead of spaces in the names, except for the .ter file; that one has spaces when it's called in the .mis file.
what am i missing? i am looking at my file, looking at the picture i see no difference? what DID you change exactly?
This terrain is too old for the new Mod Manager to handle so it needs to be unpacked. And then many of the files need to be renamed; all of the files in the main directory, except the .ter file, need to have underscores instead of spaces in their names.
