• 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.

Gen.Building Fallback Colors

Hello

my question concerns the TEXTURES of GENERIC BUILDINGS.

The texture-files (BMP) and their related texture numbers are listed in the BGLComp - SDK document "Generic Building Textures.xls" (Excel spreadsheet).

In the 2nd column under the heading "Fallback Color" quadruples of numbers (fom 0 to 255) are listed.

FallbackColors.bmp


I have searched in vain for their significance.

Does anyone know ?

Many thanks

Helli
 
Hi,

As fas as I know the numbers mean ARGB

A = transparency
R = red
G = green
B = blue

Regards,

Luis
 
Is this FS9 or FSX? A Fallback color would be the color displayed if the texture is not found. The four numbers will be for Blue, Green, Red and Alpha. (I think that is the order). The alpha channel is probably for transparency and looks always to be 255 which is solid.
 
I think you are right about that order Jon. The last is certainly the alpha, as it is always 255.
 
Thank you, all three of you.

Jon, this is the FS9 list - I am not aware of a similar list in the FSX SDKs.

But the explanations make sense. The color numbers ring faintly a bell - dating back to the good old VIC20/64 - Commodore times.

I think the best is to try it out, removing a texture and then calling it up in ObPlacer.

Yes, but on the other hand as they are default textures, they should never be missing. So I don't think the fallback color is that important for generic buildings.

Also, ObPlacer XML does not have the fallback color implemented, so this is something you can only see in FS itself.
 
Hello Arno

You are right of course.
In fact I had to remove two textures totally from my computer to find out, what FS9 would "fall back to", a situation which - as you say - should or would never occur.
With my action it did occur and the interesting fact is, that depending of the sun angle the building simply turns to various shades of gray - for both missing textures exactly the same way!

That means, the color codes in the list have some other significance.

Arno, what drives me to this small investigation is not an improvement of Generic Buildings, I like and use them as they are!
But I get restless, when someone like MS publishes a table with entries, for which there is no obvious explanation.
Then why do they publish it?

sincerely

Helli
 
For me the fallback color is only interesting for the first 4 entries, the one that have no textures at all :).
