This method works on all body typesDefines a fixed behavior for a 2D Rigidbody. Can be Dynamic (the body moves under simulation and is affected by forces like gravity), Kinematic (the body moves under simulation, but and isn’t affected by forces like gravity) or Static (the body doesn’t move under simulation). More info
    See in Glossary    , including Static bodies. It can simply calculate a new position, change the Rigidbody2D position immediately (supports interpolation), or defer the movement by automatically calling Rigidbody2D.MovePosition(). This feature makes Character ControllersA simple, capsule-shaped collider component with specialized features for behaving as a character in a game. Unlike true collider components, a Rigidbody is not needed and the momentum effects are not realistic. More info
    See in Glossary     easier to create.
  • Added the ability to use sub-stepping simulation when Simulation Mode is Update.
  • Enabled CompositeCollider2D to allow each Collider2D to select one of four composite operations: Merge (OR), Intersect (AND), Difference (NOT), and Flip (XOR), and a composite order for controlling the order that each Collider2D will be composited.

Moved Unity 6 documentation for the Universal Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary (URP) to the Unity Engine manual. For example, documentation about lighting in URP is now in the Lighting section of the manual.

Changes introduced in Unity 6 Preview

  • Added support for indirect Dispatch Rays (part of DXR 1.1). The method is similar to RayTracingShader.Dispatch, but the three dispatch dimensions are retrieved from a GraphicsBuffer. Added RayTracingShader.DispatchIndirect and a new CommandBuffer.DispatchRays signature. Added SystemInfo.supportsIndirectDispatchRays capability status.
  • Added the GPU Resident Drawer, which automatically uses the BatchRendererGroup API to draw GameObjects with GPU instancing. This reduces the number of draw calls and frees CPU processing time.
  • Added support for SpeedTree GameObjects to the GPU Resident Drawer.
  • Added support for GPU occlusion culling of instances if they’re compatible with the GPU Resident Drawer, including culling of small meshes.
  • Adding a new per-batch layer filtering setting for the BatchRendererGroup API. You can use this setting to cull specific batches.
  • Optimized CPU performance of the Volume framework in URP and HDRP, to improve efficiency on low-end hardware and allow more precise control over quality settings.
  • Added a Force No Crunch texture compression setting in Build Profiles > Asset Import Overrides, which forces all textures to disable crunch compression and re-import.
  • Added an IRenderPipelineResources interface that allows you to add new settings groups in the Graphics Settings window. Updated the default IRenderPipelineGraphicsSettings Inspector to trigger notifications when a value in Graphics Settings is modified, and added a custom menu in IRenderPipelineGraphicsSettings.

  • Added the option to cache render graph system compilation for both URP and HDRP.

Changes introduced in 2023.2

  • Unity 2023.2 introduces optimizations to SkinnedMeshRenderers across all supported platforms. These optimizations aim to batch compute skinningThe process of binding bone joints to the vertices of a character’s mesh or ‘skin’. Performed with an external tool, such as Blender or Autodesk Maya. More info
    See in Glossary     and blendshape dispatches. This can increase the amount of vertices deformed in parallel and improve the GPU performance of character and skinned mesh rendering.
  • The Progressive GPU LightmapperA tool in Unity that bakes lightmaps according to the arrangement of lights and geometry in your scene. More info
    See in Glossary     is now out of preview and fully supported. For more information, refer to Select the CPU or GPU for baking.
  • Added APIs to move Light Probe positions at runtime.
  • Removed the Auto Generate setting in the Lighting window. Related APIs are now obsolete. To check lightmapsA pre-rendered texture that contains the effects of light sources on static objects in the scene. Lightmaps are overlaid on top of scene geometry to create the effect of lighting. More info
    See in Glossary     while you’re editing, you can now select a Debug Draw Mode and set Lighting Data to Preview. This displays a preview of the baked lighting. The preview lightmaps are non-destructive, and you can use them after you’ve baked the scene.
  • Added BatchCullingContext.cullingFlags to specify whether to cull lightmapped shadow casters.
  • Added rendererPriority support for BatchRendererGroup.
  • Added support for building ray tracingThe process of generating an image by tracing out rays from the Camera through each pixel and recording the color contribution at the hit point. This is an alternative to rasterization. raytracing
    See in Glossary     acceleration structures asynchronously on a compute queue. AsyncCompute CommandBuffers can now run CommandBuffer.BuildRayTracingAccelerationStructure commands. Added support for RayTracingAccelerationStructure to RenderGraph and Render Graph Viewer.
  • Enabled exposing raytracing acceleration structure build flags for balancing build times versus ray tracing speed and memory consumption on the GPU. You can customize flags from C# when creating and building a RayTracingAccelerationStructure, or via the Renderer settings.

  • Added support for providing tiled EXR images to LoadImage.
  • Added Native Render Pass support for DX12.
  • Added support for GPU batched skinning for D3D12 (Windows and XBox platforms).
  • Added the Custom Vertex Streams feature for particle trails.
  • Added BakeTexture and BakeTrailsTexture scripting methods.

Changes introduced in 2023.1

  • Introduced a new graphics jobs threading mode called Split Graphics Jobs to reduce unnecessary start and end of frame synchronization between the main and native graphics job threads.
  • Introduced the new LightBaker v1.0 backend for manual lighting bakes, which makes baking more predictable and stable. Manual bakes no longer restart if you change the scene during baking, so the Editor is more responsive during baking. If you bake with the GPU backend, you can use a Baking Profile to select the tradeoff between performance and GPU memory usage.
  • Added screen space lens flaresA component that simulates the effect of lights refracting inside a camera lens. Use a Lens Flare to represent very bright lights or add atmosphere to your scene. More info
    See in Glossary     that you can generate from all lights visible on the screen (direct, indirect, emissive surfaces, specular highlights) in just a few clicks with a single post-processingA process that improves product visuals by applying filters and effects before the image appears on screen. You can use post-processing effects to simulate physical camera and film properties, for example Bloom and Depth of Field. More info post processing, postprocessing, postprocess
    See in Glossary     volume. These lens flares are compatible with both HDRP and URP. This feature complements the Lens Flare (SRP) component, which gives you more advanced artistic control over lens flares from lights, but which you can only use on predefined light sources (directional, point and spot lights), and can only manually associate with each one.
  • Dynamic shader variant loading provides additional user control over shader loading behavior and memory usage. This optimization enables the streaming of shader data chunks into memory, and eviction of shader data that is no longer needed at runtime, based on a user controlled memory budget. This allows to significantly reduce shader memory usage on platforms with limited memory budgets.
  • Added asynchronous compilation of pipeline state objects for shader warmup.
  • Added DirectX Raytracing (DXR) 1.1 support in compute shaders. Added the following APIs: SystemInfo.supportsInlineRayTracing, SystemInfo.supportsRayTracingShaders, ComputeShader.SetRayTracingAccelerationStructure, and CommandBuffer.SetRayTracingAccelerationStructure(ComputeShader, …).
  • Added #pragma require inlineraytracing to compute shaders.
  • Added new RayTracingAccelerationStructure.AddInstance signature that allows adding mesh instances to the acceleration structure for GPU ray tracing. This is the equivalent of Graphics.RenderMesh from the rasterizationThe process of generating an image by calculating pixels for each polygon or triangle in the geometry. This is an alternative to ray tracing.
    See in Glossary     pipeline.
  • Added foveated rendering support for D3D12/Vulkan.

Choosing a different rendering path affects how lighting and shading are calculated. Some rendering paths are more suited to different platforms and hardware than others. More info
    See in Glossary    .

  • Added support for foveated rendering in the Forward+ rendering path.

Changes introduced in 2023.1

  • Added temporal anti-aliasing (TAA) support. The feature is not compatible with MSAA, Dynamic ResolutionA Camera setting that allows you to dynamically scale individual render targets to reduce workload on the GPU. More info
    See in Glossary    , or Camera stacking. The feature supports only fixed resolution, and does not support temporal upsampling.

  • Added support for High Dynamic Range (HDR) output.

  • Added the Detailed Stats section to URP Rendering Debugger.

  • Ported all URP passes to use the RasterCommandBuffer API.

  • Added the AO Method property to SSAO settings where you can select the options Interleaved Gradient Noise or Blue Noise.

  • Added the Falloff field to SSAO settings to control the distance from the camera where the AO effect is applied.

  • Added the clustered reflection probe support to the URP Forward+ rendering path. This enables the use of more than two reflection probes per object, allows Unity to skip per-object culling of lights and reflection probes, and enables Entities Graphics and procedural draws to make use of reflection probes.

  • Added the low-code Custom Post Processing feature in URP.

  • Added Decal support to render graph API.

  • Added render graph API support to URP post-processing effects.

  • Added support for shadow rendering to 2D objectsA 2D GameObject such as a tilemap or sprite. More info
    See in Glossary    , such as sprites, collidersAn invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. More info
    See in Glossary    , sprite shape, and 2D animation.

  • Added soft shadow rendering to shadow-casting 2D lights.

  • Added a limited support of Probe Volumes, with no interpolation of lighting data sets, and limited performance on lower-end hardware.

  • Improved FXAA quality. The new implementation provides better edge anti-aliasing (removing odd edge artifacts seen with the previous implementation) and better retention of texture quality. The improvement does not affect performance. The output quality is now comparable to the low and medium SMAA presets but with better performance.

HDRP

For a complete description of new features and improvements in URP, refer to What’s new in HDRP.

Changes introduced in Unity 6 Preview

  • Added support for overriding material properties such as smoothness, albedo, and normal mapsA type of Bump Map texture that allows you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry.

  • Added the ability to use the baking API to bake Adaptive Probe Volumes (APV) independently from lightmaps or reflection probes.

Changes introduced in 2023.1

  • Light Layers and Decal Layers are now managed in similar ways in both HDRP and URP. In HDRP they now share the first 16 Rendering Layers, instead of using 8 separate bits each. Additionally, a new option in the HDRP Asset allows access to a full screen buffer that contains the Rendering Layers Masks of rendered Objects. HDRP can sample that buffer from the ShaderGraph through the HD Sample Buffer node, and use it to implement custom effects, like outlining objects on a specific rendering layer.
  • All Ray Tracing HDRP features (raytraced shadows, reflections, AO, global illumination, path tracing, recursive rendering,…) are officially out of experimental in Unity 2023.1.0.
  • Added a foam system to the HDRP Water System.

  • Improved the water rendering system in the following ways:
    • Added functionality to Water Mask so it dynamically removes water from inside a boat or in a cave in the middle of an island.
    • Modified the water deformer to dynamically deform water locally. For example, to deform water around a moving ship, deform waves near shores, or deform water in a vortex.
    • Added flow maps to create local currents, to manage surface waves that follow currents, and the water query API to allow objects to drift.
    • Added a water line to manage the transition for cameras that are half underwater.
    • Improved visual quality of water.
    • Improved the UX of the water system.
  • Added an extra optional pass to compute thickness of transparent objects at runtime to get more accurate refraction and transparency rendering.
  • Improved visual quality when using temporal anti-aliasing (TAA) with two new options to perform sharpening. The first option is a post-process pass that offers higher quality sharpening, control over the amount of sharpening, and an option to reduce possible ringing artifacts. The second option is to run Contrast Adaptive Sharpening from AMD FidelityFX.
  • Specular light can now be completely faded when using a specular color workflow using the HDRP/Lit and HDRP/StackLit shaders by toggling a new option that can be found in the HDRP Global Settings under Miscellaneous/Specular Fade.
  • Added Rendering Layers support to Adaptive Probe Volumes (APV) to address light leaking issues in interior/exterior scenarios.
  • Added a new Leak Reduction Mode for Adaptive Probe Volume sampling called ‘Quality’, which ensures that no invalid probes are sampled.
  • Implemented an anti-seam mechanism to smooth transitions between multiple subdivision levels in Adaptive Probe Volumes.

Multiplayer

Unity 6 includes updates and new features to simplify multiplayer game development.

For a complete description of new features and improvements in Multiplayer, refer to New in Multiplayer.

Package Manager

Changes introduced in Unity 6 Preview

Improved the behavior of Project manifestEach Unity project has a project manifest, which acts as an entry point for the Package Manager. This file must be available in the <project>/Packages directory. The Package Manager uses it to configure many things, including a list of dependencies for that project, as well as any package repository to query for packages. More info
See in Glossary files by repopulating them with default dependencies if the files are empty or full of whitespace.

Changes introduced in 2023.1

  • Added functionality to track assets imported from an Asset Store package:
    • Added an Imported Assets tab in the package details view (My Assets) to visualize imported assets.
    • Added a Remove button and window for Asset Store packages, to selectively remove imported assets.
  • Enhanced the user experience for deprecated packages. The Unity Editor notifies users at startup if their project has any deprecated packages. Updated the Package Manager window to identify two types of package deprecation:
    • Packages that reach their end of life and are no longer supported in the given Editor.
    • A specific version of a package marked as deprecated.
  • Added Web3 as a category in the Filters menu when viewing My Assets.
  • Changed the default sorting in the My Assets view to Purchased date, to match the default sort method in Asset Store.
  • Changed the install menu items to start with Install instead of Add.

Package cache management

Changes introduced in 2023.1

  • Changed the default location and structure of the global cache.
  • The registry data cache is now limited to a default maximum size of 10 GB. You can override the default by customizing the global cache.

Package Manager window

Changes introduced in 2023.2

  • Added a navigation panel:
    • Added a panel to improve the navigation between views of package subsets. In earlier versions, these contexts were stored in the Packages dropdown menu.
    • Added Services as a dedicated entry in the Package Manager navigation panel.
    • Added Updates as a nested entry beneath In Project in the navigation panel. This nested view lists all the packages in your project that have updates available.
    • Added individual scoped registries as nested entries beneath My Registries in the navigation panel.
  • Enhancements to the list panel:
    • Added a Packages - Asset Store expander in the list panel of the In Project context, so you can view and manage Asset Store packages from the In Project view.
    • Relocated the search box and changed its behavior so it recalls your search terms on a per-context basis.
  • Enhancements to the details panel:
    • Improved the flow for managing packages in the My Assets context by streamlining the action buttons in the details panel. The most common action appears as the default action in a menu button, with additional actions listed in the menu. Also added an In Project label to clearly indicate when an Asset Store package is already imported into your project and up-to-date.
    • Updated the label of the Import button when viewing an Asset Store package. After you download an updated Asset Store package, the main action button label is Import update #.# to project, so it’s clear that you need to import the update to your project.
    • Updated the behavior of the Documentation link for packages that you installed from a registry. You can now right-click the link and choose to Open in browser or Open locally.
    • Added a button to sign in with your Unity ID when you’re logged out and try to view the details of an Asset Store package.
  • Other enhancements:
    • Updated the values in the Filters menu when you’re viewing the My Assets context.
    • Updated the label for the Filters control so it shows the selected value rather than the parent category.

Platforms
