# MSFS 2024 glTF Format<no value>
Microsoft Flight Simulator 2024 currently supports [`glTF 2.0`](https://github.com/KhronosGroup/glTF) models, and your model assets should be created using this. Before starting, however, it is important to note that there are a number of differences between the general {{< glossterm >}}gltf{{< /glossterm >}} format and what is supported by Microsoft Flight Simulator 2024:

 

 

### Model Data

Currently there is **no support** for the following features in the model data:

-   hierarchical non-uniform scaling
-   sparse accessors
-   custom tangents

 

Additionally, for skins, *the inverse-bind matrices are ignored*.

 

 

### Images

The following caveats should be respected when adding images:

-   Only URIs to external images are supported
-   The `mimeType` parameter is ignored, unless the `image.uri` does not have an extension

 

 

### Materials

When creating materials for Microsoft Flight Simulator 2024 you should follow these rules:

-   normal maps must use DirectX conventions for normal vector packing instead of OpenGL conventions
-   texture values for roughness, metal and occlusion must be packed into the same texture

 

The following is also worth noting:

-   double-sided materials do not modify the normals when viewing the back-face of materials (i.e. the normals will always be point outwards)
-   texture sampler information is ignored (wrapping method is always `CLAMP_TO_EDGE`)
-   animation sampler interpolation method is ignored (interpolation method is always `LINEAR`).

 

Finally, note that there is **no support** for the following:

-   No support for a primitive.mode other than TRIANGLES
-   No support for the Occlusion Strength parameter.

 

 

### Custom Materials

Microsoft Flight Simulator 2024 has support for a custom material type, which allows access to a few render-specific techniques. It is therefore recommended to use the Microsoft Flight Simulator 2024 Plugin for **3DS Max** or **Blender**, especially for aircraft. You can find out more information about these plugins on the following page:
