I uploaded a world in Unity 2019 and discovered this when viewing it in Unity 2022.
The Animate Cross-fading shader effect in LODGroup was working in 2019, but not in 2022.
The LODGroup component appears to be working to animate, but the shader does not appear to be able to animate.
The area around the shader keyword
LOD_FADE_CROSSFADE
did not seem to work well in 2022, but I cannot be sure.
