Using Emissive as static lighting in a instanced actor blueprint

I’ve made an actor blueprint that spawns a spline with spline meshes and static meshes along it.

So they are basically christmas lights.

My issue is that I would like for these to bake their emmissiveness as static lighting and just can’t figure it out. I can make it work on other random static meshes that aren’t blueprint actors.
I’ve gutted my entire script and tried just spawning one static mesh and can’t get that to work using the same settings at the external meshes.

Am I doing something wrong? I am also open to dynamic lighting and my last resort is spawning static lights inside each individual mesh. static lighting is the ideal though.
