What is the easiest way to get a thumbnail image for an asset at runtime?
I need this for a level editor.
I believe GetAssetPreview() only world in the editor.
For anyone finding this old thread, there is now a nice Asset: Runtime Preview Generator | Camera | Unity Asset Store
make an editor extension that saves out all the AssetPreview to a folder with AssetDataBase.Create so you can load the png/jpg/… as texture2D during runtime
