I feel sure he won't mind me reproducing it here.

For those who enjoy the experience of instrument panel glare one minute, and blackness in the next minute - Steve has found what he calls "a gold nugget"... Back a while ago, Bojote found an innocuous fsx.cfg parameter that had something to do with cockpit shadows.... which "did nothing"... Well, Steve tried it with DX10, and guess what! It works!


So - he has put a note on his blogsite, (see Recent Posts on right) explaining how to do it - and by NOT using the DX10 ToolBox. I know there's a thousand other aircraft out there, so I did some tests this morning, and here's the list of what works, and what doesn't work. If you don't see it in the list, it's because I haven't got it, or haven't loaded it.

Tested & works:-
A2A Cub, Spitfire, C172:Aerosoft's PBY: the WACO:Ant's Tiggie:both Milviz and stock Beech Twins and the C310: the FrenchVFRFree C150-K Ti Bush & 150L: the Rick Piper Chippie: the stock Beaver: the CBFS DH89a Rapide;
Manfred's C-47 v2: the Edgley Optica: stock Extra 300: BN-2 Islander: IRIS BD-5, Christen Eagle and Silence Twister: LHMaddog (Yahoo!): the Maule & Mooney Bravo: Piglet's Pilatis PC-6: stock Piper Cub:RA SF 260: the LDR Ryan Navion: SibWings BirdDog and Pitts.

Tested & didn't work:-
MAAM B25, Do-27, SibWings Safir

New FSX Setting ForceVCShadowMap
by stevefsx
I have just stumbled across a new fsx.cfg setting ForceVCShadowMap. Jesus Altuve had mentioned that this setting existed in the past but with no explanation of what it might do.
In DX9 mode it does nothing, which I why I guess it was forgotten.

However in DX10 mode it seems to enable (force) VC cockpits for all aircraft regardless of the setting in the VC Model file.
To enable this locate the [Display] section and add
ForceVCShadowMap=1
With this setting enabled there is no longer any need to use DX10Toolbox to turn the VC Shadows on in the model xml file.
If you are using DX10SceneryFixer there is another bonus to this new setting.
If you create a profile with
Legacy Aircraft Self Shadow ticked in the Legacy Dialog
HD Shadows unticked in the Shadow Dialog
Force VC Walls ticked
Then with luck you should find that you have VC Shadows in your legacy FS9 aircraft
