AssetPreview
Utility for fetching asset previews by instance ID of assets, See AssetPreview.GetAssetPreview. Since previews are loaded asynchronously methods are provided for requesting if all previews have been fully loaded, see AssetPreview.IsLoadingAssetPreviews. Loaded previews are stored in a cache, the size of the cache can be controlled by calling [AssetPreview.SetPreviewTextureCacheSize].
