• 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.

Gauge "tearing/distortion"

Hi. I'm making a HUD gauge for a helicopter. I have an issue where my pitch/roll indicator is tearing and doing crazy shit at certain angles

When i bank the helicopter 15ih degrees the gauge will briefly go haywire.

For the gauge I'm using a panel config where the whole gauge is

set up like following:

Code: 
[Window07]
file=Hover_Gauge_Background.bmp
position=4
size_mm=225,270
visible=1
ident=10010
gauge00=HoverGauge!HoverGauge, 45,45,135,135
gauge01=PFD!pfd2, 45,180,135,90

The hover gauge is working fine, it is 300x300 in the gauge itself

The pfd is 300x200 and has a pitch ticker that is 156x1462 pixels that i rotate and shift. Is this too large? I've seen several other gauges that use these kinds of dimensions.

The PFD code so far looks like following:

Code: 
<?xml version="1.0" encoding="UTF-8"?>

<SimBase.Document
        Type="AceXML"
        version="1,0"

Try reversing the order of your Mask and Image:

Code: 
            <MaskImage id="AttMask2.bmp" Name="AttMask2.bmp">
                <Axis>150.000,100.000</Axis>
            </MaskImage>

            <Image id="pfd_pitch.bmp" Name="pfd_pitch.bmp">
                <Transparent>True</Transparent>
                <Axis>79.000,733.000</Axis>
            </Image>

The "Mask" should be drawn first, then the "Image" of the horizon drawn over it. The "Mask's" RGB:1,1,1 areas will act as a "Container" for the horizon bitmap and confine/limit its movement to only that defined area.
