I just switched from the legacy AssetBundle system to the SBP and was trying to use the CompatibilityBuildPipeline.BuildAssetBundles.
The legacy interface BuildPipeline.BuildAssetBundles would generate an AssetBundle file for class AssetManifest which could be loaded as normal AssetBundles.
However, the interface CompatibilityBuildPipeline.BuildAssetBundles generated a YML format CompatibilityAssetBundleManifest which I don’t know how to load.
