  • GPU Instancing: Instancing might get broken under glcore if graphics jobs are enabled.
  • Graphics: with the new jobs enabled, reflection probes might render incorrectly in rare cases.
  • In deferred rendering, lightmapped objects affected by mixed-mode lights will fallback to forward rendering.
  • On Windows with MSAA and Image Effects, game view can be rendered upside down
  • Shadows: Directional shadows will present shadow acnee when using a custom projection matrice and a very large frustum (20k+)
  • VR: Single-Pass-Stereo causes some lighting problems
  • [Billboard][LOD] Unity crashes when picking deleted Speedtree Billboard LOD level

  • Multiplayer: Fixed issue where default matchmaker port was 80 instead of 443 in 1 code path
  • Multiplayer: Fixed issue with matchSize being incorrectly used from a join match response
  • Multiplayer: Fixed UI panel on NetworkManager for match max size and name, as well as add in tooltip info for both
  • Multiplayer: Fixed up MatchMaker URI to be correct with http:// prefix as default
  • Plugins: Fixed Editor crash, when trying to set plugin settings for deprecated platforms.
