Least awful way to import materials from Blender?

Godot Version

Godot v4.1.3

Question

I don’t think I’m using this import feature correctly…






Not pictured: the hundreds of other error messages

Having looked up possible solutions, I heard of simply baking the materials in Blender, but it turns doing that is incredibly slow and unpleasant without paid plugins. Then I thought of editing the shaders in Godot, but my options are limited (colours on partially-transparent objects are way off as shown, can’t turn those window frames greyscale like I want etc) and .exr files are seemingly not tolerated for import either. So two questions:

  1. How do you get around this?
  2. What should I do
