Unity 5.3.0 Beta 5

Known Issues

• Editor usage of TreeCreator on OSX will hang with updated default GLCore. For workaround, use --force-opengl

Change

• Physics: Obsoleted enum JointDriveMode and JointDrive.mode
• Physics: Setting Rigidbody.detectCollisions to false also affects queries now (e.g. Physics.RaycastAll)
• Physics: When changing a mesh and subsequently setting it as the sharedMesh of a MeshCollider we now update collision mesh instead of ignoring the changes.

Improvement

• Graphics: Added custom near plane slider for spot lights instead of auto-calculation, defaults to 0.2.
• Graphics: Expose GraphicsSettings class to scripting API.
• Graphics: Implemented shadow bias for point lights.
• Graphics: Reflection cubemap convolution is GGX now.
• Graphics: Reflection cubemap convolution preserves HDR highlights better.
• Improved "The referenced script on this Behaviour" message with the game object name in the player, it will look now like 'The referenced script on this Behaviour (Game Object 'Main Camera') is missing!'.
• Integrated the industry standard for tangent space "mikktspace" into Unity. This allows artists to get seamless lighting since compatiblity is ensured between normal map baker and renderer (particular xNormal and several other bakers).
• Particles: A percentage of particles can now be rotated in the opposite direction.
• Physics: Always render the outline of a PolygonCollider2D in dark-green so that if an edge is discarded, it still shows.
• Physics: Increase precision of Physics2D.OverlapArea & Physics2D.OverlapCircle methods.
• Reflection Probes: Abiltity to turn off deferred reflections when using deferred shading. When "no support" is picked for deferred reflections in Graphics Settings, then in deferred shading reflection probes are done Unity 5.0/5.1 style (per-object).
• Reflection Probes: blurriness of glossy reflections from Realtime Reflection Probes matches Baked probes better now
• Shaders: Smoothness curve of Standard shader matches Substance Painter and Marmoset Toolbag2 (only when tools is using GGX) very closely now
• Shaders: To improve visual quality of specular highlight Standard is now using GGX distribution function. Previously Blinn-Phong was used
• Unity IAP: ProcessPurchase called from background thread on Android. Moved to the scripting thread before invoking an App's event handlers.
• WebGL: Make the path names for all output files configurable in the html

• Physics: Added tooltips for JointLimits min and max values and freespin parameter
• Physics: BoxCastAll, SphereCastAll, CapsuleCastAll now return zero RaycastHit.point for colliders overlapping with the sweep primitive at the initial position. Previously the result was undefined, which oftentimes matched the point returned by the previous sweep, but not necessarily so.
