Changes in the ASToFra tools in the last 90 days

MR [ 667 ] - 2026-03-07 20:08:24.165000

Resolve "MSFS Asobo_Props.BGL slow to load"
Fix bug that optimizing objects with bones could get stuck in an endless loop. Also fixed issue that some objects from MSFS_Asobo_Props.bgl file could not be loaded since support for skin and bone animations has been added. Closes #6847
Affected tools/features: ModelConverterX, Severity::bug, reader

MR [ 668 ] - 2026-03-07 09:13:26.108000

Resolve "Add reverse animation button to animation editor"
Added button to the animation editor to reverse all currently selected animations. Closes #6845
Affected tools/features: ModelConverterX, Severity::feature-request, editor

MR [ 663 ] - 2026-03-06 15:49:53.280000

Resolve "Select by area"
Allow selecting multiple nodes in the selection mode by dragging an area with the mouse. This also means that dragging and rotating the preview in selection mode is no longer supported, this can only be done in the navigation mode now. Closes #6840
Affected tools/features: ModelConverterX, Severity::feature-request, visualisation

MR [ 666 ] - 2026-03-05 11:46:41.372000

Crash preview select
Fixed crash when selecting a part in a model where no textures have been loaded.

MR [ 665 ] - 2026-03-04 05:02:57.403000

Resolve "Filter which materials to apply template to"
Added filter options to the apply material template batch operator, so that it can be configured to which materials from the object the template should be applied. You can for example filter the materials based on the DisplayName and DiffuseTexture, checking if these attributes are equal to or contain a certain text. Closes #6846
Affected tools/features: ModelConverterX, Severity::feature-request, editor

MR [ 661 ] - 2026-02-28 14:20:50.276000

Resolve "Support model attachments in glTF"
Added support for MSFS attached models (as defined in the model XML file). They are shown in ModelConverterX as AttachedModels in the attached object editor and the preview can render them. ModelConverterX can read them from the model XML file and does also write them to the model XML file on export. Closes #6828
Affected tools/features: ModelConverterX, Severity::feature-request, editor, reader, visualisation, writer

MR [ 657 ] - 2026-02-27 13:54:42.752000

Fix preview control bug fixes
Applied some bug fixes to ModelConverterX that were reported by another developer using the preview control in his application.

MR [ 662 ] - 2026-02-27 10:08:16.631000

Resolve "Issues reading 0 kB texture file"
Made texture loaders more robust so that a 0 kB texture file does not result in errors, instead the texture is reported as failed to read now. Closes #6843
Affected tools/features: ModelConverterX, Severity::bug, reader

MR [ 660 ] - 2026-02-27 09:09:25.412000

Resolve "Jetway exported incorrectly"
Fixed some issues exporting FSX/P3D jetway models Closes #6370
Affected tools/features: ModelConverterX, Severity::bug, writer

MR [ 659 ] - 2026-02-23 06:52:17.621000

Resolve "Use bone pose matrix when exporting to MDL"
When exporting to a MDL file, which does not store a bone pose matrix, ensure that the correct pose is part of the mesh geometry. This ensures that skin and bone animated objects imported from formats like glTF or FBX can also be exported correctly to MDL files. Also added a material template to set the skinned mesh attribute of the material to true when the material is used on a part that has bone weights. Closes #6818
Affected tools/features: ModelConverterX, Severity::bug, writer

MR [ 658 ] - 2026-02-20 16:33:00.531000

Fixed mistake in deploy pipeline

MR [ 656 ] - 2026-02-20 15:16:02.496000

Resolve "Build as self contained application"
Build and deploy ModelConverterX and scenProc as self contained applications, which means that the required .NET version is part of the application now and does not have to be installed by the users. As part of this change LibraryCreatorXML and FXEditor have been integrated into ModelConverterX and scenProcBatchRunner and scenProcWorker have been integrated into scenProc. Closes #6839
Affected tools/features: ModelConverterX, Severity::feature-request, scenProc

MR [ 655 ] - 2026-02-07 09:05:45.265000

Add MOB difference tool
Added MobDiff tool to visually compare two MOB files. This tool is not part of the ModelConverterX release and is only used to help debugging while developing ModelConverterX.

MR [ 654 ] - 2026-02-07 08:04:10.872000

Add ModelConverterX Object (MOB) format
Added new ModelConverterX Object (MOB) format that can be used to export the internal ModelConverterX representation of an object to file and also import it again. This can be useful if you want to store the state of your object without exporting to one of the flight simulator formats. If the embed texture option is selected the textures of the objects are also stored in the format.
Affected tools/features: ModelConverterX, Severity::feature-request, reader, writer

MR [ 620 ] - 2026-01-30 11:27:50.312000

Resolved: "FBX export animations"
Added feature to export animations to the FBX format via Assimp. Both node animations and skin and bone animations are supported. When the object has been loaded from a MDL or BGL file, animation export is only possible with the export animations license (similar to how glTF animation export works).
Affected tools/features: ModelConverterX, Severity::feature-request, writer

MR [ 653 ] - 2026-01-25 07:55:29.527000

Resolve "Write skin and bones to glTF"
Added support to write skin and bone animations to glTF files. The bones and skin weights are always exported. For exporting the bone animations the same restrictions apply as for exporting animations to glTF files. Closes #5776
Affected tools/features: ModelConverterX, Severity::feature-request, writer

MR [ 645 ] - 2026-01-24 10:44:14.004000

Resolve "Read skin and bones from glTF"
Added support to read skin and bone animations from glTF files. glTF files processed by the MSFS package tool do sometimes have parts that use skin and bone animations that are still displaced. This is because the package tool does add some optimization that I don't fully understand yet. This will hopefully be solved in the future. Closes #5761 Closes #6834
Affected tools/features: ModelConverterX, Severity::feature-request, reader

MR [ 652 ] - 2026-01-24 07:57:17.702000

Resolve "MDL parts with wrong scale"
Fixed issue that certain MDL parts got wrong scaling in scenegraph optimization. Closes #6837
Affected tools/features: ModelConverterX, Severity::bug, reader

MR [ 650 ] - 2026-01-17 09:19:22.221000

Resolve "Option to include alpha in unwrap texture"
Added extra checkbox to the unwrap texture creator form that determines if the alpha channel of the original texture is copied to the unwrap texture. Closes #6833
Affected tools/features: ModelConverterX, Severity::feature-request, editor

MR [ 651 ] - 2026-01-17 08:19:18.990000

Resolve "System.ComponentModel.Win32Exception while starting process with link or file
Fixed issue that opening external links and files from the tools did sometimes give an error because the existing code was not compliant with the latest .NET version. Closes #6835
Affected tools/features: ModelConverterX, Severity::crash, scenProc

MR [ 648 ] - 2026-01-11 19:59:35.782000

Resolve "Parts displaced after scenegraph optimization"
Fixed bug in object scenegraph optimization that could result in parts being displaced. Closes #6832
Affected tools/features: ModelConverterX, Severity::bug

MR [ 647 ] - 2026-01-11 12:17:38.237000

Resolve "redistributable error"
Added option to disable the redistributable check in ModelConverterX (at start up and before using compilers like XtoMDL) to be able to proceed (at own risk) when the check gives a false error. Closes #6816
Affected tools/features: ModelConverterX, Severity::bug, writer

MR [ 646 ] - 2026-01-11 09:03:58.038000

Resolve "Texture resize function is slow"
Performance improvements to the texture resize function. This function is e.g. used to generate mip maps when the input texture does not contain them. Therefore this optimisation will speed up loading a new model in the preview. Closes #6831
Affected tools/features: ModelConverterX, Severity::bug

MR [ 640 ] - 2026-01-09 17:16:10.350000

Resolve "Emissive color not shown in preview"
Update the shader of the ModelConverterX preview to use the emissive color of the object as well. For PBR materials the rendering mimics MSFS, for non-PBR materials it mimics FS2004. FSX and P3D do not store the emissive color in the MDL file, so this feature is less relevant for these simulator versions. Closes #6820
Affected tools/features: ModelConverterX, Severity::bug, visualisation

MR [ 644 ] - 2026-01-09 12:30:05.268000

Resolve "Remove close button from options form"
Remove the close button from the Options and Texture search path forms to force users to use the OK or Cancel button to close it. When pressing the close button (X) at the top, changes were not saved. Closes #6815
Affected tools/features: ModelConverterX, Severity::feature-request, UI

MR [ 643 ] - 2026-01-09 10:25:02.936000

Resolve "Animation editor text missing"
Made sure that the full text of all buttons in the animation editor is shown correctly. Closes #6825
Affected tools/features: ModelConverterX, Severity::bug, UI, editor

MR [ 642 ] - 2026-01-08 20:16:18.255000

Resolve "CTD loading model"
Fixed endless loop in logic to search for textures that occurred when texture.cfg files have a circular reference. This endless loop resulted in a CTD of ModelConverterX. Closes #6830
Affected tools/features: ModelConverterX, Severity::crash, reader

MR [ 641 ] - 2026-01-05 06:13:59.052000

Resolve "Long animation tweak bug"
Fixed issue that applying long animation tweak to a FS2004 MDL file without animations would result in an invalid MDL file that could not be loaded anymore. Closes #6821
Affected tools/features: ModelConverterX, Severity::bug, writer

MR [ 639 ] - 2026-01-05 06:13:31.303000

Resolve "redistributable error"
When checking for the C++ 2005 redistributable that the FSX XtoMDL needs, allow both the RTM and the SP1 version. This is a workaround for users where the RTM version can be installed, but the SP1 version gives an error. Closes #6816
Affected tools/features: ModelConverterX, Severity::bug, writer

MR [ 635 ] - 2026-01-04 13:02:14.994000

Resolve "Export texture with UV mapping"
Added an unwrap texture creator function that can generate an unwrap texture based on the loaded object. It can be opened via the special tools menu or via the texture tab context menu in the material editor. Closes #1439
Affected tools/features: ModelConverterX, Severity::feature-request, editor

MR [ 638 ] - 2026-01-03 21:30:30.842000

Removed code quality warnings
Added more checks for potential code quality issues to the build pipeline. And applied fixed for certain common issues.

MR [ 637 ] - 2026-01-03 19:57:06.947000

Resolve "Model zoom/orientation not correct"
Fixed bug in scenegraph optimization that resulted in attached object being displaced (especially for FS2004 aircraft), which resulted in the initial zoom/orientation to be calculated wrong. Closes #6819
Affected tools/features: ModelConverterX, Severity::bug, reader

MR [ 636 ] - 2026-01-03 15:14:23.824000

Roslynator
Added Roslynator code quality checker to the build pipeline.

MR [ 634 ] - 2026-01-03 10:34:52.163000

Resolve "Aircraft shown as transparent"
Fixed issue that entire model was shown transparent when loading certain FS2004 aircraft models. There was an issue in the way that ModelConverterX combined the diffuse colour alpha value with the texture. Closes #6817
Affected tools/features: ModelConverterX, Severity::bug, reader

MR [ 573 ] - 2026-01-02 05:59:27.594000

Resolve "Read skin and bones from FBX"
Added support to read skin and bone animations from the file formats that are read via the Assimp library (COLLADA, FBX, ...). Closes #5753
Affected tools/features: ModelConverterX, Severity::feature-request, reader

MR [ 632 ] - 2025-12-30 21:26:49.170000

Resolve: "Crash after loading empty model XML file"
Fixed a crash that would happen when a model XML file was loaded that contained no valid objects and therefore returned an empty scenery.
Affected tools/features: ModelConverterX, Severity::crash, reader

MR [ 631 ] - 2025-12-27 08:58:37.533000

Resolve: "Crash loading incomplete glTF"
Fixed crash when loading a glTF model that only has the BIN file and is missing the glTF file.
Affected tools/features: ModelConverterX, Severity::crash, reader

MR [ 630 ] - 2025-12-27 08:57:32.830000

Updates of NuGet packages
Updated various NuGet packages, including Assimp, GDAL and EmguCV, to their latest version. Closes #6805
Affected tools/features: ModelConverterX, scenProc

MR [ 629 ] - 2025-12-24 07:54:54.099000

Resolve "Normalize all model textures at once"
Allow items from the scenegraph node context menu in the hierarchy editor to be selected when multiple nodes are selected. This way operations like normalize texture coordinates, flip texture coordinates, smooth shade, etc. can also be performed on multiple nodes at once. Also added an option so that the texture coordinates of the entire model can be normalized directly on import of a model. Closes #6811
Affected tools/features: ModelConverterX, Severity::feature-request, editor

MR [ 628 ] - 2025-12-22 21:11:54.746000

Resolve "Add rotate with wind tweak"
Added Rotate with wind tweak that can be selected when exporting a FS2004 scenery MDL like the other tweaks. It will automatically rotate the object in the wind direction. Closes #6812
Affected tools/features: ModelConverterX, Severity::feature-request, writer

MR [ 627 ] - 2025-12-20 23:00:05.906000

Resolve "Select mode does not work after rotate"
Fixed bug that after rotating object the select mode did not work correctly anymore. Closes #6810
Affected tools/features: ModelConverterX, Severity::bug, editor

MR [ 625 ] - 2025-12-20 22:29:05.536000

Resolve "Add FS2004 MDL tweaking"
Enable the following ASM tweaks to be applied when exporting a FS2004 scenery MDL. The tweaks can be enabled with the options in the export object dialog. - No shadow: the model will not give a shadow in FS2004. - Rotate to user: the model will always rotate towards the user in FS2004. - Long animation fix: this enables animations with more than 1024 frames to work correctly in FS2004. - Seasonal textures: add seasonal textures to the object (this tweak is not controlled with an option in the export object dialog, but automatically applied if a material has the HasSeasonalTextures flag set). Closes #697 Closes #6807 Closes #6808
Affected tools/features: ModelConverterX, Severity::feature-request, writer

MR [ 612 ] - 2025-12-19 20:48:51.409000

Resolve "Remove remaining fixed pipeline elements"
Removed the last remaining bits of the fixed pipeline OpenGL from the 3D preview logic. This means that the preview is now fully shader based. Closes #6746
Affected tools/features: FXEditor, ModelConverterX, visualisation

MR [ 621 ] - 2025-12-19 19:47:17.697000

Set the version of the development release to 1.9.
Affected tools/features: ModelConverterX

MR [ 626 ] - 2025-12-19 17:44:14.732000

Resolve "Attached effects do not show in FS2004"
When effects are near the edges of the object bounding box FS2004 does not always show them. ModelConverterX will add an invisible box around your object to prevent this issue when exporting to FS2004 MDL. Closes #6809
Affected tools/features: ModelConverterX, Severity::bug, writer

MR [ 624 ] - 2025-12-10 20:36:47.326000

Improvement auto-generated source files
Improved pre-build logic to generate certain source file automatically during build.
