Modular Building And Lighting
First, I want to apologize because I know this has been asked a million times before but I have a question about modular building and lighting. I am not one for building houses and what not so I bought the RealisticHouseKit from the marketplace (pretty great by the way) but I noticed that once I use the directional light, atmospheric fog and all that to "build" my sky, I notice the seams and weird shadows on my walls and floors.
I know this has to do with UV wrapping and changing the lightmass settings can help a little bit but my question is this: When I set a point light or something like that in my scene and set it to dynamic, everything is seamless and looks exactly how you would expect it to so, is there a non performance killing way to emulate the sky and sunlight coming through my windows? I assume that setting every light to dynamic would kill performance.
Also, I am kind of regretting going the route of modular building now that I know all of the issues that UE4 has with it.
Thanks in advance!

" the seams" probably UnitScale/IndirectLighting Settings in the World Settings https://forums.unrealengine.com/development-discussion/rendering/17760-lightmaps-and-seams
"weird shadows" make sure that there is a production build and a proper UV, and I know that you know it, but first of all you need check this, also check ligtmap resolution of the asset and light channel for UV. In UE you can have perfect realistic scene with a proper world and uv settings https://www.youtube.com/watch?v=8kir1O0X8bs
yes, dynamic light can killing - you can turn off dynamic shadows from all object that shouldn't receive this, also you can put dynamic lights and objects (which need to have those lights) to different channels (skylight not working with channels), many lods, and spot lights with skybox if possible.
Best way if you use dynamic scene - using hism on your modules, but lighting quality will be not so rich (even with lpv and dfao) as static light if you don't using RTX of course, but it's killing too.
