because UE4 is used a lot for architectural simulations I’m trying to simulate real architectural lighting with photometric data.
I noticed that is not possible to create asymmetrical lights and it’s very difficult to orient ies lights in space.
Imagine to light a museum with hundreds of pictures and sculptures. You can’t orient your lights picking the target point, because it doesn’t exist in UE4. The camera light positioning is a trick and it’s a time consuming process.
Recently wall washer lights are used as emitters to wash uniformly entire walls or facades.
In UE4 is not possible to see the spatial distribution of a ies light.
I understand that UE4 was born for games but we, architects, want to build our virtual spaces closely as much as possible to reality.
