To avoid trouble when running multiple instances on one machine, disable
e.g. joystick input for second instance by
--prop:bool:/sim/input/no-joystick-input=true
Also allowed:
--prop:bool:/sim/input/no-event-input=true
--prop:bool:/sim/input/no-mouse-input=true
--prop:bool:/sim/input/no-keyboard-input=true
required SimGear commit 75271c44a82ae0fb1ff9c91e93a12fa8b10099fd
Since the consensus seems to be that the precipitation clipping issue is with the panel code, attached is my proposed update for the precipitation system in SG and FG
* without corresponding control structures in FGData it falls back to default, except I have fixed an inconsistency in freezing behavior - previously rain changed suddenly to snow when the temperature dropped below zero, but the reverse transition was dragged out and gave odd visible motion with the wind as snow gradually changed back to rain with the particle speed not well defined. Now both transitions are sudden. And I see no more particles flow against the wind
* with
<!-- definitions for the detailed precipitation manager -->
<precipitation-control>
<rain-droplet-size type="float" userarchive="n">0.015</rain-droplet-size>
<snow-flake-size type="float" userarchive="n">0.03</snow-flake-size>
<detailed-precipitation type="bool" userarchive="n">false</detailed-precipitation>
<illumination type="float" userarchive="n">1.0</illumination>
<clip-distance type="float" userarchive="n">5.0</clip-distance>
</precipitation-control>
added to Environment/environment.xml, the new system allows to switch more detailed management on. This provides
* explicit setting of rain droplet size and snow flake size by the weather system
* automatic sqrt(r) scaling of the vertical speed of raindrops
* automatic transition to snow when freezing for small droplets but hail for large droplet sizes (looks like snow, but has different particle dynamics)
* an illumination scaling factor to dim the precipitating based on the light we have in the scene (I still need to devise a property rule to set this automatically)
The clip distance is also exposed now and considered at startup of the system - might be useful for e.g. airships when the gas bag provides rain cover (?) or to be simply off for open airplanes
- Introduce a new LOD: ai-interior
- Load a <model> with <usage>interior</usage> on-demand
- Avoid to load the cockpit of players in MP
- Default LOD is 0.0 - 50.0 meters
Adds new option --load-tape=foobar to load a flight recorder
tape from the command line. Loads foobar.fgtape from the
directory specified in /sim/replay/tape-directory and starts
replay.
the static system has an optional "tau" parameter to
define the rate at which the output value changes.
Setting this value to zero now disables the filter.
This prevents wrong airspeed indications on rapid
altitude changes. No functional changes if tau has
other-than-zero values (e.g. the default systems).
write the vertical flight path to /orientation/path-deg
zero means level flight, positive angles climb
Also use SGD_DEGREES_TO_RADIANS (and vice versa) for double computations
instead of the float constants
Also allow events on desktop group if no window is receiving
events. Currently it is not possible to prevent events handled
by the desktop group to further propagate (eg. to normal
control input).
