Backbone batching on cocos creator 3.4.2 – Cocos Creator

On cocos 2.x, i used spines on similar layer and use batching. However on cocos 3.4.2 i cannot discover allow batching for backbone. How i can get again this function once more. Any assist are all valuable, thanks

Creator 3.4.2 doesn’t present this function once more, the aim of batching is to enhance efficiency, after model 3.4.1 the 2D rendering framework has been tremendously improved, subsequent variations may also enhance efficiency by different means (not restricted to batching operations).

Thanks you for the reason
