Subject: Ensure that the aircraft model is in the same clip plane as everything
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=d254b2a331df0062dd5fd9c1014da71bed753c63;p=flightgear.git

Ensure that the aircraft model is in the same clip plane as everything
else and *doesn't* clear the z-buffer when in external view; tighten
the far plane for internal view back to 100m to give us maximum
precision (this will be important for some instruments; I might even
move it to 50m).
