If you use this unofficial version of the ASOBO exporter, be aware that you will need to or it is highly recommended that you migrate your MSFS materials. They will NOT display with the Migrate Data button. However this exporter has a number of shader node, shader node link changes and default factor value changes. These changes will only be utilized if you reselect the MSFS material. That is, reselect the same MSFS material from the drop down - DO NOT SELECT DISABLED in the drop down. Please make a backup of your original work before migration.

If you want to go back to using the ASOBO exporter, this may or may not be possible. First if the blend file is a version higher than what ASOBO uses, there may be issues with animations or other blender data where you will be required to rebuild the object and/or animations. If ASOBO has released a version that uses a Blender version equal to or higher than what you currently are using here, then it would be easier to migrate the material nodes to the new ASOBO version by re-selecting the MSFS Material Param type in the drop down

This repository contains the current version of a non-official Microsoft Flight Simulator Blender Import/Export plugin. The flight sim community has already developed and forked the original project many times, and Asobo's intention is to fully support Blender with the help and contributions of all the developers that have already implemented features in the different unofficial Blender plugins.

⚠️ This plugin is a fork of the ASOBO plugin version 1.3.2 - and has the following mods/fixes

v1.6.2.x (Blender 3.3.x and 3.6.x) v2.0.1.x (Blender 4.0.x)

#213 Emissive strength - mod and default values change - max 100

#214 Parallax - mod bug fixes (should work)

#220 Projected Mesh invisible in Simulator - not fixed

#248 Multiple empty animations on export - you must manually checkboxes

#252 Vertex Color Rainbow - mod applied - fixed

#266 Glass and standard render in sim differently - with same parameters. - not fixed

#269 Comp textures are not being included from saved v292 .blend files - fbw migration added to help fix this

#279 Addon defaults to a base color value of 0.8 - modified numerous default values.

#280 Blender Exporting ERROR (Long Code) - core Khronos code issue - not fixed

#281 Exporter doesn't take collections in account - not fixed

#284 Current XML are being completely overwritten on export - not fixed

#289 Color Attributes (Vertex Painting) wrong in shader - mod added

#290 Add function - To delete all glTf Settings.xxx and reassign to Proper glTf Settings - mod added

#291 Jetway wheel animation not working - not fixed

#294 Enhancement - Change RGB Curves to show Blue channel as all 1's (white) - mod added

#8 not export emission day night cycle extension - fixed bug introduced

Some default values for Metallic, Roughness, Emissive, Base Color have been reset Max emissive strength now 100 (not the same a Emissive Factor) Vertex Color added to exported data and now shows in Blender - Shader nodes added with links Normal - Blue Channel set to default to 1 (White)

Added more functionality to the migration of materials. If you import a glTF file using the fbw (Fly-By-Wire) importer, you will get material nodes that are not one for one in synch with the ASOBO exporter and a Pre-Migration will be required. The fbw materials will now carry over it's data to the new ASOBO shaders with better accuracy. You will still need to monitor the migration of those materials.

Asobo would especially like to thank the following people: Vitus of Wing42, tml1024, ronh991, pepperoni505 of FlyByWire

⚠️ This plugin cannot import glTF files that have been built into a Microsoft Flight Simulator package through the Sim's Package Builder.

⚠️ This plugin is NOT compatible with the legacy exporter developed for FSX and P3D and MSFS. Remove these plugin (Prefered) or disabled these plugins.

⚠️ The version 1.6.2.x is only compatible with Blender 3.3.x LTS up to 3.6.x LTS. Other versions are not supported.

⚠️ The version 2.0.1.x is only compatible with Blender 4.0.x. Other versions are not supported.

There are two ways to install the MSFS Blender exporter. Either using the Edit Preferences Menu and Install tab, or copy/paste the addon files to your %APPDATA% folder. Installation steps are explained down bellow :

1. Go to the Releases section of the https://github.com/ronh991/glTF-Blender-IO-MSFS/releases repository. Then download the zip file io_scene_gltf2_msfs_for36.zip for Blender 3.6.x or the pre-release version io_scene_gltf2_msfs_for40.zip for Blender 4.0.x.

2. Open Blender and go to : Edit > Preferences.

3. Go to Add-ons and click on Install an add-on. This will bring up a file dialog, where you navigate to the folder where you have your io_scene_gltf2_msfs.zip downloaded file.

4. Select the io_scene_gltf2_msfs.zip file. And click on the Install Add-on button.

5. Enable the Add-on by clicking on the checkbox.

1. Close Blender if you have it open.

2. Go to the Releases section of the https://github.com/ronh991/glTF-Blender-IO-MSFS/releases repository. Then download the zip file io_scene_gltf2_msfs_for36.zip for Blender 3.6.x or the pre-release version io_scene_gltf2_msfs_for40.zip for Blender 4.0.x.

3. Decompress the contents of the file to a temporary location.

4. Select the io_scene_gltf2_msfs folder then copy it to the clipboard (Ctrl + "C").

5. Now browse to the Blender addons folder, which - by default - can be found in the following locations:

   • Windows: This will usually be in %AppData%\Blender Foundation\Blender\<blender-version>\scripts\addons\.
   • Mac OS X: This will be in your Library (Press the Option key when in Finder's Go menu to open your Library folder): \Users\<username>\Library\Application Support\Blender\<blender-version>\scripts\addons\.

6. Paste the io_scene_gltf2_msfs into the Blender addons folder (Ctrl + V).

After completing the process outlined above, you will need to start Blender and then activate the plugin. Activation is done from Edit > Preferences, as shown in the image below:

NOTE : You may need to restart Blender again after activating the plugin for all the options to be visible in the IDE.

1. If you previously installed the Microsoft Flight Simulator glTF Extensions Add-on, Remove/Delete the older version using the Blender Edit > Preferences Menu.

2. Select the Add-ons tab. Search for the Microsoft Flight Simulator glTF Extension Importer/Exporter add-on in the search box. Delete the Import-Export: Microsoft Flight Simulator gltf Extension using the Remove button. :warning: DO NOT DELETE THE Import-Export: gltf 2.0 format Add-on.

3. You should now have only the Import-Export: gltf 2.0 format addon left.

4. Close the Blender program.

If you want to learn how to use this add-on you can refer to the documentation page here : Documentation for Microsoft Flight Simulator glTF 2.0 Importer and Exporter for Blender

You can also have a look at the SDK documentation of the plugin here : https://docs.flightsimulator.com/html/Asset_Creation/Blender_Plugin/The_Blender_Plugin.htm

Shadertree modification directly impacts the result of the exporter. The properties of your material must only be modified through the MSFS Material Panel section.

⚠️ If you work with an MSFS Material you should never modify the shader tree manually.
