Please, update the hint and online documentation of the “Forward Shading Priority” property of directional light (ForwardShadingPriority).
Nowhere in the hint or the official documentation it says in which direction priority goes.
ForwardShadingPriority | Unreal Engine 5.5 Documentation | Epic Developer Community
Priority is such an ambiguous world, it is vastly used as ascending order, where lower number means higher priority, like “this is our number 1º priority”, which gets override by an emergency that usually goes with “this is our priority 0 (zero)”. So between 5 and 7, 5 will run first.
But it is also used as descending order, where higher number have priority over lower number. So between 5 and 7, 7 will run first.
The only reasonable comment about this property is on a reddit post

According to the comment, it uses higher run first, so between 5 and 7, 7 will run first.
So please, be explicitly about which direction this game priority goes.
