    Enlighten UE4 3.11 Release Notes

    Dec 22, 2020

    Changes in 3.11.R (UE4.25.0)

    Key Features

    Support for next generation platforms:

    • PlayStation 5
    • Xbox Series X
    • Stadia™

    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.

    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.
    • 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.

    Known issues

    • This release does not include support for mobile platforms.
