UI, Ordering & Batching - How to get lower draw calls

Hi, almost everyone must know about batching.
I am making 2D game and I need to make it faster now. Big problem is UI system.
I found that even I use same atlas, batching not work on buttons, sliders and even on all elements what are not in same level (index).

Is there any way how to batch successfully texts and graphics but leave the nice structure of parents and childs?
Batching always fail when elements not in same "folder".
I have now 2 draws for game and 20-50 draws for UI.

 

Here are a few links that might be of interest.

Thanks,
I made some progress and lowered Batches from 30-40 to half.

Problem is still with sliders amd fonts but i think i will make it.

I have another question: I see that Dynamic Batching incerasing CPU usage. For Android mobile is better to have Dynamic Batching enabled and have low amount of batches or disable it and have lower CPU usage. What is better for FPS and Battery usage.

 

Hi,

Did you managed to reduce the batches?

I'm encountering the same problem, my batches breaks, even-though they shouldn't (because the items in the same hierarchy level)...

Any tips?

 

Try to make their Zs same.
