Blender - Principled BSDF to MSFS Material Params

This script converts from Principled BSDF to MSFS Material Params in Blender, for use with Microsoft Flight Simulator GLTF Exporter

How it works

It's was created with the workflow of importing SketchUp models with the Sketchup Importer for Blender, but might work with other imported meshes too.

As SketchUp only supports diffuse maps, it will convert from Principled BSDF Base Color to MSFS Material Params Base Color. It will try to find the NORMAL and ARM (Ambient Occlusion, Rooughness and Metallic) maps from the Base Color texture file name by searching the texture_path variable. For example (and by default): if the Base Color texture map is called Wood_DIFFUSE.png, it will try find the textures named Wood_NORMAL.png and Wood_ARM.png

To use other naming schemes, see below.

How to use

1. Load converter_sketchup.py in Blender's Scripting tab
2. Change the variable texture_path to the path where your other texture maps are located
3. Change the suffix_ variables to the suffixes you use for those maps. This script will try to automatically find the NORMAL and ARM maps based on the base color map
4. Run the script
