Importing Blender file yields no vertex colours in Godot

Godot Version

4.1.1

Question

In Blender (ver 3.6.0) I have baked a material consisting of an image texture node (containing a brick texture) and a color attribute node (containing selective vertex painted shadows). The outcome of this is that I have, quite logically, a brick texture with shadows which can be seen in the following blender project file:

When I import the .blend project file into Godot the brick image texture appears appropriately however the vertex color shadow has disappeared, as per this image:-

Why is Godot not able to include and display the vertex color shadows?

Any help understanding what is causing this discrepancy would be appreciated.

Godot can import vertex colors, but it won’t import Blender’s materials exactly the two programs use totally different rendering pipelines so any success converting materials is on a best guess basis; you will have to re-create the material in Godot, a StandardMaterial3D usually has all the settings you will need for PBR
