Lightmap + RealTimeShadow

Please forgive my poor English.
I have two directional lights.

A bake only Light. (cullmask default layer) (all static object and terrainObject)

Ohter RealTime only Light. (cullmask dynamic layer) (Role Object)

But in the scene, only Lightmaping shadow.(Terrain in Default Layer)

RealTime Dir Light does not work.((Role in Dynamic Layer))

who can help me?

And this issue is very much like, but I did not get the answer.

Yes, Unity Pro.
If I just use Realtime-shadow.
Everything has a shadow.
But with Lightmap, the terrain is not receiving the projection of the dynamic object.
Any ideas?

Do you have Unity Pro? If not, it’s no wonder you can’t use real-time shadows.
