Changes in 3.11.R (UE4.25.0)

Support for next generation platforms:

Early Access: Enlighten indirect lighting for Rect Light actors.

Basic Rect Light properties are supported, including Source Width, Source Height, Barn Door Angle and Barn Door Length.
Cast Enlighten Shadows option is not currently supported: this may cause light leaks where a Rect Light illuminates a thin wall.
The Source Texture property is not currently supported.

Enlighten indirect lighting for a Directional Light with Atmosphere/Fog Sun Light enabled.

Enlighten indirect lighting for materials which use the Hair shading model.

Reduced render thread time spent on Enlighten updates in D3D11 when using per pixel probe lighting in combination with Reflection Capture actors that Use Enlighten.
For a SpeedTree asset, the precompute now defaults to use the lowest-detail non-billboard LOD for Enlighten radiosity.

Nintendo Switch: Significantly reduced Enlighten runtime update cost for Reflection Captures with Use Enlighten enabled.

D3D12: Fixed unexpected high Enlighten update overhead on render thread in a level containing many Reflection Capture actors with Use Enlighten enabled.
Fixed a warning "Non-deterministic cook warning" when cooking a level which contains a Light actor.
Fixed Enlighten data asset being incorrectly marked modified after loading a level which contains Landscape Grass.
Fixed a shader compiler error during a full recompile of all shaders.
Fixed a D3D12 resource leak error when the UE4 editor is closed.
Fixed an intermittent crash in Foliage Edit mode when foliage instances are deleted.
