Compositor

17 May 2020 16:44 #46665 by Algernon
Has anyone successfully had Compositor running with shadows in ALS? I found the fgfs-compositor.exe binary and have tried running it, with two properties ("/sim/rendering/als/shadows/enabled=true" and "/sim/rendering/als/shadows/sun-atlas-size=2048") specified in FGRun but not seeing much difference, and definitely no shadows. To use the ALS pipeline, I think you have to specify something in the command line, but I'm not sure you can do that with FGRun...

Have tried to follow the notes here but not getting anywhere - guidance would be appreciated! :)

Try adding

--compositor=Compositor/als

to the command line.

Yeah, I have been trying to figure out how to do that - I use FGRun to launch, and though you can see the command line it generates, you can't edit it. I've tried creating a command line entry by copying the one from FGRun and sorting out the paths and stuff, but I can't get it to find any aircraft.

Try something like:

--fg-aircraft=d:\FlightGear\FGUK\Aircraft
--aircraft=EF2000

I use Linux and the Qt Launcher so can't tell you exactly.

using --compositor=Compositor/als in my fg run does turn it on, according to the console, compositor is active, yet I see no shadows.

How do you put that in FGRun? On the end of the .exe in the first page?

On Windows you would put it to the properties of the desktop icon like this.


And these two settings go to the additional settings of the launcher:

--prop:bool:/sim/rendering/als/shadows/enabled=true \
--prop:int:/sim/rendering/als/shadows/sun-atlas-size=8192 \

Pretty impressed with The Compositor so far - shadows are great (as Stuart demonstrates above) and this is a point light on the airframe (the red lines are the debug visualisation of the light volume).

One thing to note - OSGText seems to be gone from the Compositor-enabled .exe, or at least does not appear when the Compositor is running. I don't think too many aircraft use it, but the EF2000 cockpit is super heavy on OSGText and it's always been a bit of a thorn in my side, hence the move to Canvas for its scheduled replacement, the Typhoon Tranche 3.

Have been talking to Alex, who's been talking to Richard, about doing text with Canvas. I'm gonna wade in. Expect me to be... volatile... for a few days ;)

2 things that aren't rendering correctly on compositor

Particles

OSGText

I think they are going to fix them

Tested with the 412, which has 3000 lines of code in its warning panel, which uses osg text. Its non functional.

OK Stuart, didn't know you used it that heavily. Let's hope they are planning to fix it, then.

I'm trying to move away from it as I've had a number of issues with it, but the alternatives do not seem to be simple or quick :(

Took me a bit to find the post saying they were intending on fixing both particles & OSGtext in compositor

forum.flightgear.org/viewtopic.php?f=4&t...ilit=osgtext#p367989

Should be it

Hope they fix it. I cant face re writing that warning panel again. It took me 10 days the first time.

Yeah, it would be an absolutely huge job :(

If it's going to fix OSGText for Compositor does that mean I'll get OSGText back on my Linux machine? I'd love for the warning panels to actually warn me of stuff! :D

OK...one more time *slowly* for old people - Just installed 2020.1.1 and I'd like to play with this compositor deal as well. What do I put where in the plain old launcher to enable it and thanks in advance!
