Build Package doesn't update changes to mesh or materials

Hi. I am pretty new to MSFS development. I have been exporting with success the model I am working on for some time while running some tests.

I am now trying to define the materials and doing some exports to try different things.

Suddenly the changes are not always updated. Some materials appear and some not. I am trying to use detail maps.

I am using Blender. Any idea what I might be doing wrong? Any special requirements for materials and detail maps?

Thanks in advance

It looks like the building breaks when trying to use detail maps in the material…

Can you use detail maps in aircraft materials?

Found the solution:

Needed to detach the UV node from the detail nodes in the shader window in blender and it worked.

It is strange that the nodes don’t need to have any output in Blender shaders to still work in MSFS.
