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.

Enlighten indirect lighting for materials which use the Hair shading model.
Important changes
- 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.
Other changes
- Nintendo Switch: Significantly reduced Enlighten runtime update cost for Reflection Captures with Use Enlighten enabled.
Fixed bugs
- 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.
