Draw call on 2 meshes 1 material.

I have two meshes(game object) that share 1 material. (exactly same shader, texture, config values)

And each of them is child of some bone that is animating. (like sword or shield)
so it is moving.

I found that the draw call of the meshes is 2 not 1.

As far as I know, meshes of the same materials have to be 1 draw call.

Am I missing something?

Here are the few rules you should follow for dynamic batching to work at Unity - Manual: Draw call batching

Also try using the vertex lit shaders or mobile/bumped diffuse if you are using normal map.
