• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

    Need some help understanding terms

    In my case, I'm using P3D's PDK to create an external flight model (the sim doesn't fight back that way) so I'm having to code everything myself. So this is more to understand the math behind things rather than how to do it in a particular sim.

    Need some help understanding terms

    Hi guys I'm working on a simulation of the Hydra 70mm rocket and need some cues on what's going on here. As labeled, these are the aerodynamic roll moment coefficients. I'm guessing Clp is the roll damping moment provided by the fins and I am guessing 1/rad means that I multiply by the roll...

    Querying DirectInput button status

    I'm not sure how you are using DirectInput, but in my experience it is not event based (at least, I have never attached a window handle to it). I use the device->Poll function every sim frame for each device followed by device->GetDeviceState function which outputs a struct containing all axis...

    Scenery Claimed

    Leborsim == Ricobrac it seems. I would guess that what the OP is seeking is for some independent dev here to review his scenery vs Leborsim and lend their credibility to convincing Simmarket that Leborsim's claim is invalid.

    FS2004 Color Banding and Background Bitmaps

    I only figured it out when we started getting the same banding in our cockpit lighting in P3Dv4 which uses raw DirectX11 shader based rendering direct into D3D11 surfaces. A chat with the LM devs revealed that they had switched to sRGB image format and then the penny dropped.

    FS2004 Color Banding and Background Bitmaps

    Actually, FSX does support 32bit colors. The problem is actually caused by the conversion to sRGB. Normalize the RGB values to 0-1.0 and pow 2.2 on them and it will get rid of the banding although your colors may need re-working.

    FSXA how do i build a synthetic vision PFD gauge ?

    The D3D11 SVS in FSX was mine. I used SSE intrinsics and a separate thread for doing the rendering and transfer to the gauge. It provided fairly good framerates, the separate thread removing the load that would have been placed on the main thread. It became obsolete when PDK appeared though.

    P3D v4 Help Needed with Combined Mach and IAS Linear Tape Gauge

    Your best bet is actually to use a material script with dynamic UVs and a static polygon.

    Setting Data on Simobject

    If you make a dummy RequestDataOnSimObject call on sim start which is set to return the data every sim frame, you have a callback function executed at that time slice in your SimConnect callback, where you can call your SetDataOnSimObject.

    MSFS -Everything you know about upcoming Flight Sim from Microsoft-

    @rhumbaflappy actually the larger 3rd party developers are in as much dark as the rest of you. There is a lot of uncertainty as to whether we will actually get what we need.

    Will there be a P3D V5?

    Multiple major addon devs (I work for one) including those who are in the commercial and military training market (again I work for one) disagree with you on the P3D part. Unfortunately your opinion doesn't match reality. It is better to remain silent and be thought ignorant than to open your...

    Calling multi-smoke entries

    I wouldn't use execute_calculator_code. I would use trigger_key_event to write (KEY_SMOKE_ON/OFF events) and aircraft_varget to read (use the index parameter to read the state of the desired channel).

    Fuel-air ratio does not set

    Its another one of those sim vars which the SDK claims is settable but isn't. I mask mixture events from the sim and redirect them into my own code, while I control the mixture lever sim var instead and monitor the fuel air ratio to get it where I want it.
