Question How to bulid a scene used dots animation?

I try to build a scene used clipplayernode.but failed and has an error:

error CS1061: 'BlobAssetStore' does not contain a definition for 'GetClip' and no accessible extension method 'GetClip' accepting a first argument of type 'BlobAssetStore' could be found (are you missing a using directive or an assembly reference?)

so how do i to use other method to translate AnimationClip to BlobAssetReference<Clip>? And then not only work in editor but also work after build too.

 

Hi,

I found a thread here: https://forum.unity.com/threads/how-to-bulid-a-scene-used-dots-animation.1074427/, but I don't think that contains really the solution
