• 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.

Backlit Gauges?

I am new to this and wanted to know why you don't see more planes with backlit gauges? It seems to me that alot of planes could benefit from them.

I am new to this and wanted to know why you don't see more planes with backlit gauges? It seems to me that alot of planes could benefit from them.

Are you refering to backlight gauges on the 2d panel or in the virtual cockpit?

For gauges on the 2d panel, the individual elements within the gauge may be coded to use either LUMINOUS or BRIGHT tags.

LUMINOUS attribute is additive, and derives it's specifications from the panel.cfg entry cleverly named Luminous=R,G,B (where R,G,B are units of color).

BRIGHT attribute effectively doubles the 'brightness' of the bitmap uniformly, although one can also specify a replacement bitmap to which they've applied a "Lighting Filter" in Photoshop or PSP.

If you are speaking about virtual cockpit backlighting, that is a 'feature' of the model itself, and the designer must specify that a lightmap be applied to the Material properties used for the gauge polys. If the modeler fails to take the necessary steps to allow backlighting, there's nothing that anyone can do to "force" the issue.

Now, FSX appears to offer a new method of virtual cockpit backlighting that I haven't figured out yet... but, the 'old method' I developed three years ago will still work. :)

For details on VC Backlighting using Emissive Lightmapping, see my ancient tutorial at http://www.freeflightdesign.com/tutorials.html
I do most of my flying from the vc. I will have to try to add it to my own design. I am thinking about doing a LSA. I haven't decided which one yet but I am leaning towards the Cessna because I work there.
