+- `Vector3.UnprojectRayToRef` has been moved to `Ray.unprojectRayToRef` instance method to decrease class coupling ([Sebavan](https://github.com/Sebavan))
+- `Material.ParseMultiMaterial` has been moved to `MultiMaterial.ParseMultiMaterial` to decrease class coupling ([Sebavan](https://github.com/Sebavan))
