Does variants work with prefabs in scene?

Summary:
I have a scene in a bundle. The scene has a prefab. The prefab is in other bundle, with two variants.
The scene always load the same prefab, regardless of the variant

Does variants work with prefabs in scene?

Additional Info
The scene has four prefabs:
Prefab 1: Variant a and b only differ in the texture. It works
Prefab 2: Variant a and b only differ in the material. It works.
Prefab 3: Variant a and b are totally different prefabs. It is loaded and instantiated in runtime. It works
Prefab 4: Variant a and b are totally different prefabs. Prefab is in scene when the scene is loaded

Thank you

 

when you build, any prefab in the scene is unpacked ("baked" as plain gameObjects). prefabs don't exist at runtime.
if you want variants (or just being in a different bundle), you need to instantiate dynamically

 

Yes, that's the problem. Thank you.
