That is not the case, dynamic lights show in either mode, What is the range of the dynamic light verses the static light you are trying to use in combination?
You can test this out by placing some room, set a static light and make it yellow, set its range to 1000. Move it to a corner.
Now place a dynamic light in the opposite corner. Make it red.
Place a box in the middle of the room.
Set a start marker.
Run test game and do a F4 lightmap on the level.
When that is complete, then go into the metric mode (tab tab) and here is what controls what.
Shadows slider controls the amount of the baked process to show thru. Turning this up will enhance the static light bake on the level.
Adjust the ambient level down a bit till you can just make out detail in the shadows.
Adjust the surface level to bring out detail in the objects.
playing with these settings will give you a balance between static baked and dynamic real time.
Now look in the room and notice how the lights are distributed. and the shadows.
Readjust the lights if needed to enhance the lighting.
