Where did "Ensure correct normals" go from the material settings in Godot Engine 4?

Question

When porting my test project to Godot Engine 4 Beta 2, I ran into a problem with my 3D models! Materials do not work correctly at all, and for the sake of justice - this was also in Godot Engine 3, but then I was able to fix this problem by enabling the item "Ensure correct normals" in the settings of the material, now there is no such a setting! Where did it go, and how do I use it now?
Godot Engine 3 "Ensure correct normals":

Godot Engine 4 Beta 2:

Also when I tested this model on Alpha versions of Godot Engine 4 - there was no such problem, "Ensure correct normals" was probably active by default

Answer 1

Ensure Correct Normals is no longer needed in 4.0, as the correction automatically happens for non-uniformly scaled models.

You're hitting an unrelated issue which isn't related to normal scaling: https://github.com/godotengine/godot/issues/64854

See comments for a workaround.
