Fixed bugs

  • Fixed an intermittent GeoPrecomp2 process hang during the precompute on some machines.
  • Fixed rare black probe lighting artifacts that could occur close to thin walls that separate disconnected areas.
  • Fixed failure to fall back to sky lighting in game mode when both persistent level and first loaded sub level have no Enlighten data.
  • Fixed failure to fall back to sky lighting in game mode for actors spawned by a blueprint.
  • Fixed failure to fall back to sky lighting in game mode when Enlighten Bounce Distance is non-zero.
  • When the density of Enlighten probes is too high, the precompute now reports the correct location of the highest density.

  • Fixed a crash after reimporting a static mesh asset that is open in the Static Mesh editor with Enlighten Charts view enabled.
  • Fixed invalid lighting for foliage with detail lighting mode on platforms with manual vertex fetch disabled.
