The only reference for 2024 ground materials should be this, right?
There are some problems indeed
A “normal roughness”
isn’t so common, so the 2020 reference about the correct slots for composing it would be helpful (x-y normal and so on) (containes in this page that has been stripped out in 2024 docu)
The metal channel seems to have been removed from the texture, maybe because metal is not supported?
If you plan to make improvements/adjustment
I would make sure that people use very faint normals,
Because the in-game rendering of them is exaggerated (especially when the sun is low over the horizon the normal creates very dark shadows)
“Second” textures materials slot are not explained in the docu
The material inspector description shows “normal roughness” only, while in 2020 docu is “normal roughness metal”
