Question about Skeletal Mesh Draw Calls


I’ve looked everywhere for an answer before posting but no luck.

So I have this example on a completely empty map, with nothing at all.
I added a simple skeletal mesh cube with one bone, it has 2 simple materials. Using stat SceneRendering it shows 6 draw calls.

Testing with the same cube but this time it’s a static mesh the result is 3 draw calls. This one makes sense.

My question is, how come the skeletal mesh has 6 draw calls ? From what I understood from other topics it should be 1 draw call per material and maybe 2 for the skeletal mesh, so 4 ?

Thank you.
