how do you import worldmachine files to terragen since i keep getting errors from not being compatible file formats
That is odd! What error message appears, exactly? is it “This is not a Terragen terrain file” ?
If so, make sure you output the file in WM using the output device with “terragen” selected and not “Leveller”. “Leveller” also produces a *.ter file, but the format is different, so Terragen is bound not to “eat” it.
