    I've just upgraded to Unity 2021.1.1f1 HDRP
    getting message with terrain - is this related?

    The package cache was invalidated and rebuilt because the following immutable asset(s) were unexpectedly altered:
    Packages/com.unity.terrain-tools/Editor/TerrainToolbox/Materials/TerrainVisualization.mat

    which is also with this warning>>>
    Importer(NativeFormatImporter) generated inconsistent result for asset(guid:05b9a38dd90fbaa4aa4bacef38c03e4f) "Packages/com.unity.terrain-tools/Editor/TerrainToolbox/Materials/TerrainVisualization.mat"
