Where is the "registeredSpriteAtlasTags" In Preview 4?

In Preveiw 3 ,there is a “registeredSpriteAtlasTags” property in Sprite which can solve my problem.See Access RuntimeSpriteAtlas from sprite - Unity Engine - Unity Discussions
But I can’t found it or in Preview4 and Unity 2017 beta7,It looks like Unity2017 will ship the final 2D Atals release.Is this property removed forever? I really need it.

Currently that has been removed. Could you provide more details how you were using it? I read the post you linked, maybe a bit more detail in the process would help us understand the usefulness. :slight_smile:

I wrote a demo to explain why I need atlas infomation (tag or reference) from a sprite,check out the attached file and run test scene.

The key code :

void LocalizedSpriteRenderer(SpriteRenderer sptRenderer, Language language) {
        string atlasName;
        //solution 1 : get atlasName from a custom record :(
        atlasName = sptRenderer.GetComponent<CustomAtlasRecord>().SpriteTag;
        //if we have a property like Sprite.tags,I will not need a CustomRecord :)
        //atlasName=sptRenderer.sprite.tags[0];//most sprite only have one tag

        //make atlasName to localized AtlasName
        var localizedAtlasName = language + "/" + atlasName;
        //load atlas from Resources
        var localizedAtlas = Resources.Load<SpriteAtlas>(localizedAtlasName);

        //get correspond sprite
        string currentlySpriteName = sptRenderer.sprite.name;
        sptRenderer.sprite = localizedAtlas.GetSprite(currentlySpriteName);
        sptRenderer.sprite.name = currentlySpriteName;//... why a sprite get from atlas called xxx(clone) :(
    }

BTW: Where is the " Runtime swap atlases and automatically rebind with loaded sprite renderers " feature ,the roadmap show it ,but can’t found.
