Godot中导入的spineDrawCall过大的问题
Davide 只有一个图集页面（尺寸小于2048*2048），我正在试着逐级排除问题的源头。我又使用texturePacker工具将spine中使用的散图导出为spine格式的图集给godot，但依然没能合批。或许问题的源头不在spine导出的设置上，而在于godot中。我在godot中尝试使用相同的材质（如shaderMaterial、CanvasItemMaterial）给spine但都无法合批。我尝试询问了AI但没能找到AI所说的一些选项。
如果没有能解决godot合批spine的方法，或许godot用户就要被迫使用godot自带的骨骼动画工具了，这对spine工具的忠实用户以及spine官方都是一个损失，希望在此问题上能得到官方工程师的协助。
We cannot help you if you don't send us a minimal reproduction project of your issue, as I said above.
Many users use spine-godot without any issue with draw calls.
@gyzbean Thanks for preparing a reproduction project. As Davide said above, you can send it to contact@esotericsoftware.com.
Harald I uploaded it to GitHub, including the Godot and Spine projects

This is a limitation of Godot. They currently do not implement batching for 2D triangle meshes.

We've worked around this as best as possible, by using meshes explicitely:
EsotericSoftware/spine-runtimesblob/4.2/spine-godot/spine_godot/SpineSprite.cpp#L173
However, that does not help with draw calls. It does improve performance compared to canvas_item_add_triangle_array though.
Note however, that Godot 4+ uses Vulkan as the default renderer. Batching is much less impactful there, which is one of the reasons it hasn't been implemented by Godot yet.
