• 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.

Editing bmp file problem

I can create photo scenery in SbuilderX but I would like to edit the base .bmp file to remove some issues. When I use GIMP to edit the file and then export it as a .bmp and then try to compile it again in SbuilderX it will not compile. The command box flashes up for just a second and it disappears. How do you properly edit that .bmp file? Is there something that needs to be done after you edit it to make it work in SbuilderX? Thanks in advance for the help.
 
Assuming you have not changed the total number of pixel rows and columns of the aerial imagery BMP file, and that GIMP is configured to Export a '"Windows BMP image" file format when changes are made to any derived copies of that original "base" BMP file output by SBuilderX, one must see what errors are generated when FS SDK Resample attempts to compile a BGL.

This can be done by opening a Windows CMD mode task session, and manually starting a compilation of your project "Photo01.INF" file via a copy of FSX SDK Resample placed inside:

[SBuilderX install path]\Tools\Work\ sub-folder

...so that you can see any error messages generated by FSX SDK Resample in that CMD mode task session window.

[EDITED]

Alternatively you can make a CMD mode 'batch' file in ex: Windows NotePad saved with a *.BAT file extension, then 'run' it by double-clicking it in Windows explorer ...as discussed in this thread:

[END_EDIT]


I suggest following the example work-flow using GIMP in: :pushpin:

https://www.flightsim.com/vbfs/showthread.php?250762-How-to-create-photoreal-scenery-for-FSX


FYI: SBuilderX creates a 1-piece BMP and a matching TXT Geo-referencing 'world' file when one performs these steps:

1.) SBuilderX Menu > File > Add Map > From Background ...

2.) Select desired aerial imagery area, then download all tiles as directed in "Add Map From Background" dialog

3.) Select desired aerial imagery area from resulting aerial imagery Background displayed in SBuilderX work-space

4.) SBuilderX Menu > File > BGL Compile ... < DO NOT 'click' [Compile] button >

5.) SBuilderX pre-assembles a 1-piece aerial imagery L*.BMP and a matching L*.TXT Geo-referencing 'world' file in:

[SBuilderX install path]\Tools\Work\ sub-folder

...without having actually compiled a BGL. ;)


That "base" BMP is the source for all derived copies of your selected aerial imagery tile area to be used for Water & Blend masks, seasonal imagery etc..


NOTE: Pixel dimensions and file names must match all definitions SBuilderX writes into a "Photo01.INF" file created during a completed BGL compile to: :alert:

[SBuilderX install path]\Tools\Work\ sub-folder


Alternatively one may copy all the above cited output files into a separate project sub-folder, edit the source and *.INF files, then compile manually.


Hope this helps with the learning process for working with files derived from the SBuilderX aerial imagery tile down-loader. :)

Gary,

Thanks for the reply. I was actually following this tutorial which I believe you pointed me to some months ago. The issue was that when I was exporting my modified .bmp file from Gimp I was not checking the 'do not export color space information' box. Checking that I am able to export and use in SBuilderX, the modified .bmp file. Thanks again for all your help.
