No shadows or Sunlight hitting my floor or wall

Hello All,

I’ve been working on a small interior scene, but I’m having problems
getting shadows to work on my floor. Also no direct sunlight is casting on
my floor or light hitting my walls from my windows.

I have done the following:

4.18.3 build

-second uv lightmap channel for ligthmaps set to 1024 and 2048 for my floor.
-Ligthmass build set to Production
-Lightmass important volume
-Lightportrals for windows
-reflectionBOX capture
-skylight (3 bounces) (static/stationary)
-directional light (static/stationary)
-Postprocess ( turning it on and off) no results.
-render set to EPIC

What could be causing this? Thanks in advanced.
