UnloadAsset on a Sprite does not unload the texture

Is this the intended behaviour?

If I call Resources.UnloadAsset(spriteRef.texture) it will unload the texture. If I call Resources.UnloadAsset(spriteRef) it will not unload the texture.

There are NO other references to that sprite or texture in the scene.

Thanks!

I'm not sure if this is intended behaviour, but I ran into the same thing and was surprised! Definitely a good thing to know!

If we assume that the UnloadAsset function can't/won't take dependent assets into account, then it means in this case that, yes, you'll need to unload the Texture separate from the Sprite.

A variation on this is how UnloadAsset doesn't work with GameObjects/Prefabs. To accomplish this sort of thing with GameObjects, you need to destroy/null references to the prefab and then call Resources.UnloadUnusedAssets(). The same thing works in this case (call UnloadAsset on the Sprite and then UnloadUnusedAssets to get rid of the texture), though it seems like overkill.
