help with camera dat tweak file

i was trying to get a higher view from the external free camera but none of the values i change has any effect in the game.

i would like to get the camera view to go as high or near as high as the visual range will allow. i love being able to get a birds eye view of a task force or convoy moving along.

so far i have changed:

freemove maxheight from 70 to 100 and then 1000

cameraparams fardistance from 10,000 to 50,000 and then 100,000

cameraparams clipdistance from 0.1 to 0.5 and then 1

none of these changes had any effect that i could notice in the game.

after each change i tried i returned the value to its original number before going on to the next value so that i wouldnt inadvertantly mess something else up.

is this not very high view hard coded now?

i could swear that it had much higher views before patch 1.3 or am i wrong?
