Changes in 3.12.P1 (UE4.26.0)
Key features
- Enlighten texture updates take significantly less time on PS5 and Xbox Series X.
- Significantly increased responsiveness of probe visualisation in a world which contains many probes.
- Reduced Enlighten Probe Memory stat when probe lit objects and adaptive probe volumes exist within many different streaming levels.
- Enlighten Probe visualisation spheres far from the camera now appear larger to ensure they are clearly visible.
- The editor now reports a warning in the Enlighten Errors window after the precompute for each mesh that was used for radiosity and has a large number of small triangles relative to the cluster size.
Fixed bugs
- Fixed precompute error for level that was originally created in UE4 without Enlighten.
- Fixed an intermittent crash that could occur during the precompute when a mesh has an extremely large cluster size.
- Fixed a use after free crash that could occur when a streaming level is loaded and immediately unloaded.
- Fixed precompute warnings incorrectly reported as errors when using SNDBS2 distributor.
- Fixed incorrect Enlighten indirect lighting for Sky Atmosphere in a level which contains a Scene Capture 2D.
- Fixed slow save for a level which contains a large number of foliage instances and was saved many times.
- D3D12: Fixed bright flash visible in Enlighten reflections when indirect lighting is changing.
- Fixed unintended modification of the level package by the Enlighten precompute commandlet when level contains UChildActorComponent and Enlighten data is stored in a separate asset.
- Fixed missing or incorrectly placed probes when the probe regions within a single zone cover an extremely large volume of space.
- Fixed division by zero exception in per pixel probe lighting runtime update.
- Fixed missing link to actor related to lightmap UV packing warnings in Enlighten Errors window.
Known issues
- This release does not include support for mobile platforms.
Changes in 3.12.R (UE4.26.0)

Fixed bugs
- Fixed meshes with negative scale shown incorrectly with orange front faces in the Radiosity Back-faces visualisation.
- Fixed missing indirect lighting for Rect light on some platforms when Barn Door Angle is below 88 degrees.
- Fixed intermittent precompute failure when Windows regional format set to a language other than English, Japanese or Chinese.
- Fixed a crash when per pixel probe lighting is enabled and probes are placed very far from the origin.
- Fixed a crash after the precompute when the world contains two identically named levels.
- Fixed a crash when the world contains two identically named levels precomputed separately.
- Fixed a warning "Duplicated Enlighten ID" and incorrect lighting in a level which contains more than one actor based on the same static mesh blueprint.
- Fixed a warning "failed to resolve archetype object" during hot reload of a class derived from UPrimitiveComponent.
- Fixed a precompute error for a level which contains an Enlighten reflection capture actor and has Disable Enlighten checked.
Known issues
- This release does not include support for mobile platforms.
