Subsurface shading gradient disappear when static lights baked

the title may look confusing. I’ll try my best to explain.
I made a material for a lantern mesh, just a mesh looking like a bowl. I changed the shading model into subsurface and set pure red to base color and subsurface color. set opacity to 0.5. That’s it.
I gave the material to mesh and placed it in the scene and placed a static light within. It started to look this, just what I expected.

But I haven’t baked light yet since it’s static light I have to bake it before launch. So I baked it then all that effect was gone
