5.4 Packaged Build lighting Dark, no skylight

Hi all.

Having issues with a packaged build lighting difference from the editor. please look at the example video.

Unreal Engine 5 2025 12 20 13 03 59 03

its as if the skylight is doing nothing at all. tried adding atmosphere, directional light and its the same outcome.

even if i put the skylight to 50 intensity its the same.

Why is the viewport so very different to a packaged build?
