• 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.

SBuilderX and Blender 2.79

For some reason tonight when I import a satellite photo from SBX into Blender 2.79 as images as planes and choose units as Imperial/feet, put the LAT/LONG in to ModelX coordinate converter then input the width and length into the dimensions into Blender 2.79 something seems not right

Using Google Earth to get my building measurements I then input that into the blender cube dimensions for the cube I need a certain size for but it blows the cube way to large.

My Units is scaled to 1.0, Does anyone have an idea on what could be wrong and how to fix it.

Thanks
Randy

It more than likely not the units. It is most likely that the scale and rotation needs to be reset.

Images from SBX are lat-long projection in degrees. The sim requires images projected as meters, not degrees. I suspect that the image will not be right. QGIS can give you an image correctly projected, which should line up well.

Hi Dick:

Would I be correct that for purposes of imagery in MSFS, EPSG:3857 is what is required since we are not dealing with a 'vertical datum' terrain mesh projection here ? :scratchch

If so, the 'under-documented' SBuilderX option can output a Geo-referenced non-warped 1-piece *.BMP for a background in a 3D modeling or airport design application.


I have previously tested / verified this easy work-flow to do that using downloaded imagery tiles in SBuilderX. :idea:

To output a 1-piece *.BMP of selected tiles from the SBuilderX work-space in a non-warped format for use in ADE or a 3D modeling application:

1.) SBuilderX Menu > Edit > Edit INI file... (SBuilderX.INI opens in NotePad)

a.) In NotePad > SBuilderX.INI > Under [Tiles] section, Edit:

ReprojectMercatorTiles=True

...and change it to read:

ReprojectMercatorTiles=False

b.) NotePad Menu > File > Save

c.) NotePad Menu > File > Exit

2
.) SBuilderX Menu > File > Add Map > From Background

a.) Follow usual procedures to download / select tiles (do not compile to BGL)

3.) SBuilderX outputs non-warped format 1-piece *.BMP / *.TXT into:

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



NOTE: For use in ex: ADE, that 1-piece *.BMP must first be processed in ex: GIMP to make either numerous smaller tile segments, or very low resolution 24-Bit JPGs, so they can be "Added" as "Images" in ADE using UTM Metadata for use as background imagery 'tiles' loaded 1-at-a-time while working on the corresponding local area of KCCR in ADE.


CAVEAT: Restore normal SDK Resample compatible output of a 1-piece *.BMP of selected tiles from the SBuilderX work-space in a warped format for use in making ex: custom photo-real imagery land class terrain textures:

1.) SBuilderX Menu > Edit > Edit INI file... (SBuilderX.INI opens in NotePad)

a.) In NotePad > SBuilderX.INI > Under [Tiles] section, Edit:

ReprojectMercatorTiles=False

...and change it to read:

ReprojectMercatorTiles=True

b.) NotePad Menu > File > Save

c.) NotePad Menu > File > Exit



AFAIK, alternatively, one may use SAS Planet which also has GIS projection options for output of stitched tiles to make a 1-piece satellite image from downloaded tiles:

Hope this helps with these types of FS development tasks. :)
