Lightmap skinned mesh not supported?

Doesn't skinned meshes bake lighting when set to static anymore? I'm using skinned meshes to animate some buttons in a 3D menu but they doesn't bake when set to static.

 

Somewhat confused.

I think skinned meshes are sort of not static by definition? You should create a static mesh if that's what you want. Probably more efficient that way anyway, if you don't plan on the thing moving or animating (and if you do, why would you want it static or lightmapped for that matter?)

 

I have buttons on a 3D menu that are gonna be animated with some slight scale and movement and I don't want to bake everything and set them to be not static every time I make a change. So I made them into skinned meshes with one joint instead to avoid this since Unity 4.6 baked skinned meshes that were set to static.

It even says skinned meshes should be lightmapped when set to static in the documentation.

 

Why SkinnedMeshRenderer has Lightmap Parameters?
