Changes

  • Cache Server: Will now by default write cache to current working directory, and not to some location in user folders.
  • Cache Server: Added --path command line option to set cache location.
  • Cache Server: Added --size command line option to set maximum cache size in bytes.
  • iOS/Android: Android Target Graphics setting is not bundled with iOS Target Platform setting anymore.
  • License: Generic external version control (.meta files) are now available in the free version.
  • Lightmapper: Inspector for LightProbes.asset no longer gives access to all the data and displays the probe count instead. Debug inspector allows only for editing the coefficients.
  • Native Client: Added Physics stripping checkbox for smaller build size.
  • NavMesh: API Changed : NavMeshAgent.DistanceToEdge() renamed to NavMeshAgent.FindClosestEdge().
  • NavMesh: API Changed : NavMesh.SamplePosition : reversed arguments for maxDistance, acceptMask (to be consistent with physics).
  • NavMesh: API Changed : NavMeshAgent.GetCurrentOffMeshLinkGameObject() and NavMeshAgent.GetCurrentOffMeshLinkData() are replaced with: NavMeshAgent.currentOffMeshLink and OffMeshLinkData.offMeshLink.
  • NavMesh: NavMeshAgent radius, height and baseOffset are scaled by transform scale values (consistent with CharacterController). Adding component to gameObject sets appropriate NavMeshAgent dimensions.
  • NavMesh: Better handling of assigning invalid values to NavMeshAgent properties (speed, acceleration etc.)
  • NavMesh: Default settings changed for baking NavMesh and NavMeshAgent radius=0.5 height=2.0.
  • NavMesh: Bake configuration of tile edge length removed.
  • Shuriken: Added tool tips to all properties and module headers.
  • Shuriken: Added ParticleSystem.IsAlive() function to API which can be used to find out if particle system (or any of its children) are alive.
  • Shuriken: Added local space option to Force over lifetime module.
  • Shuriken: Added Min Kill Velocity to Collision module.
  • Shuriken: Renamed elements in API: ParticleSystem.Particle: energy now called lifetime and startEnergy now called startLifetime.
  • Shuriken: Renamed ParticleSystem.startEnergy to ParticleSystem.startLifetime.
  • Shuriken: Dampen in Collision Module is now inverted (consistency with limit velocity module).
  • Social API: Added a LoadUsers function for fetching user profiles for given user IDs.
  • Social API: Refactored all classes into a UnityEngine.SocialPlatform namespace, except for the main Social class itself. You now need to use/import the SocialPlatform namespace to use Achievement/Score/etc classes (and they all now derive from interfaces). Implementations (like GameCenter) are placed into their own namespace as well but you only need to use/import them if you need functionality, provided by the implementation, which is not in the generic Social API.
  • Social API: Renamed UnityEngine.SocialPlatform to UnityEngine.SocialPlatforms, and GameCenter class to GameCenterPlatform.
  • Social API: Corrected various inconsistencies in API names (like Score.playerID instead of Score.UserID)
  • Social API: Added GameCenterPlatform.* functions for resetting achievements and for showing the default completion banner (iOS 5.0+)
  • Social API: Added factories for leaderboards and achievements

Known Issues

  • Editor: due to bug in img tech pvr compressor textures with alpha are forced to be compressed with Normal compression quality
  • Flash : ReadPixels and SetPixels can cause crashes. SetPixels should only be used with small textures until a proper fix is in place.
  • In 3.5 the behaviour of when to add an extra root node containing imported nodes has changed. Previously it was based on if there are multiple root nodes and in order to fix issues where character animation files had only one but the model had multiple, it was using the @ notation files to figure out when to add multiple root nodes. Now the logic is simply: if any of the root nodes have a rigged bone attached or if there are multiple root nodes.
    This fixes a lot of issues in animations. In some rare cases it might lead to animations not play when importing, they can be fixed by matching the number of bones in the animation fbx file to the fbx file that contains the model.
