1. Open the attached "LODGroupCrossFadeIssue.zip" project
2. Open the “SampleScene”
3. In the Hierarchy, select the "GameObject"
4. In the Inspector, under the "LOD Group" component, change "Fade Mode" to "Cross Fade"
5. Tick on "Animate Cross-fading"
6. Change "Fade Mode" back to "None"
7. Change "Fade Mode" to "Cross Fade" again
