Unity Patch Release 5.5.0p3

Release notes


  • Shaders: During shader compilation if an unknown/unhandled error occurs append the unknown/unhandled error message to the shader compiler error message. This gives some context on what might be wrong in the shader.


  • (none) - Ads: Fixed cloud build issue.
  • (835453) - Android: First scene is now loaded asynchronously while the splash screen is displayed.
  • (none) - Animation: Renabled StateMachine multithreaded evaluation.

  • (858235) - Particles: Fixed crash in CopyFromArrayAOS when calling Emit(position, velocity, size, lifetime, color).
  • (856877) - Particles: Fixed error in TLS Allocator ALLOC_TEMP_THREAD when simulating particle system.
  • (none) - Particles: Fixed rare memory overwrite which would have caused problems (crashes) in random areas eg memory managers.
  • (856871) - Particles: Game crashes when new particles are spawned using deprecated Emit method
  • (856224) - Particles: Particle System Lights Module would not generate lights if particle positions were modified by script.
  • (852817) - Particles: Particle System Renderer wouldn't allow rendering using multiple materials.
  • (846516) - Particles: Particle System subsequent Sub Emitter inherit properties were overridden with the first inherit property.
  • (851712) - Particles: ParticleSystem editor was using incorrect handle matrix when scaling mode was set to Hierarchy.
  • (850638) - Particles: Unity could crash in EmitterStoreData function when a Particle System was "aligned to direction" during Play mode.
  • (858816) - Physics: Fixed interpolation of Rigidbodies causing position and rotation to be inaccurate when accessed via Transform from within FixedUpdate.
