MSFS20 Unable to create MSFS_Standard Material via Python

[connomar]

I am working on a project that will generate ground markings automatically. One thing I got tripped up by early on was that MSFS requires a textured plane, rather than a vector colored plane for the Scenery/PolyMesh.
I have got very close to my objective, whilst learning Python at the same time, so the errors are harder to trace.
The issue I am facing is that whilst one can see the code steps that result from manually create the material, making it msfs_standard and attaching the texture file, when doing this in code,
:
bpy.context.object.active_material.msfs_material_type = 'msfs_standard'


I get the error:

AttributeError: 'NoneType' object has no attribute 'msfs_material_type'

I can find no documentation to this effect, but it seems likely that there should be an import or a from statement that links to the exporter. Does anybody have any idea.

msfs_standard, like all the rest of the sim materials are an ASOBO extension to gltf. You would have to bring in all the ASOBO python files and reference those and then build the material. This is a very simplistic suggestion. It would be a lot of work.

Thanks Ron,
Looks like I will have to manually create the materials. What a pain, it was going so well too.

@connomar I just ran this code and it executed fine on a single object. The MSFS material type changed in the side panel.

This error is most likely occuring because the selected item(s) you are running this code on does not/cannot have any material assigned to it.
For example a lamp, or, more than likely from the "NoneType" error, it is an empty.
If you are running this code on a selection of items, first verify that the current object is in fact a MESH. This will filter out any NONETYPE/other objects that do not have the attributes you are trying to change.

for o in bpy.context.selected_objects:
        if o.type == 'MESH':
            ...your code here...

Thanks so much for giving me hope.

Hello again,

Please could you send me the exact code you used to test this, because I am getting nowhere. I am only a few weeks into Python, and this is the first big project. I have over 100 textures files to link to materials and place on planes, so I really don't want to do it manually, plus, I want to beat this thing.

Thanks
Martin

That is great, thanks so much.
