Why is my baked lightmap not shown in the meshes?

I have these test meshes, they are all set to static, have lightmap UV generated. Lit using a point light that are set to baked with shadow enabled. After baking they are all just black in shaded, have I missed somet$$anonymous$$ng?

I can see the baked lightmap from Scene>baked lightmap, it's just seems they are not applied?

T$$anonymous$$s is how they look before light map baked

and t$$anonymous$$s is after, I used PLM and t$$anonymous$$s is the setting
