I conducted a test with the software creation of texture modes based on the post @Thaumaturge
https://discourse.panda3d.org/t/simplepbr-no-normals-or-emission
And I found out that it does not work as expected. I repeated the values from the Egg file.

Maybe I missed something. Also, for GeoMipTerrain, you will need to take care of tangents.
