Pick up any regex txt editor and change all <max_elevation>.*</max_elevation> instances to <max_elevation>90</max_elevation>. Do the same with min_elevation, changing all the instances to -90.
Notepad++ is a nifty little editor with simple regex search and dest... um, replace. In the example above, . is any alphanumeric character and * indicates it'll accept 0 or more instances of it. In other words it'll accept any value (positive or negative) inside max elevation tag. Extremely nifty and absolute must have for anyone modding or modmodding.
That being said, you can always pick up mod-moded versions of Tonicmole's camera mod right away Just remove secondary extension (.v1 / .v2) and you're golden. Mod-modded so that in any scenario you can look straight up or down. Hope you won't mind, Tonicmole!
It's all good. More the marry......er
