This is our next attempt at lighting from a higher floor ( 29th Floor ) and quite a challenge when there’s no portals or skylight. I think I was using Unreal Engine Version 4.9. I was using a huge spherical geometry that is texture emitting for environment lighting, a bit of an old school method . At the time I was happy with this type of lighting but I found better lighting methods (. Again, the geometry is very simple as it was a request from our interior designers - changes does happen a lot.
