A newer version of Unity has been released since Unity 1.5

Unity 1.5

A newer version of Unity has been released since Unity 1.5. Check out the current release notes to find out what's really new.

Major New Features

Feature #1: Windows web-browser plug-in

With the new Windows web browser plug-in, Unity web games are ready for prime-time. Just create your content normally, then use the File -> Build Settings... menu to take your web game live.

Your games will get the attention they deserve.

Feature #2: Character Animation

Unity 1.5 has a brand new animation system. It now supports animation blending, mixing, additive animations, walk cycle time-synchronization, animation layers, control over all aspects of the animation playback (time, speed, blend-weights), and mesh skinning with 1, 2 or 4 bones per vertex (can be controlled with quality settings) – in addition to our classic ragdolls.

But don't let the buzzwords scare you – it's still easy to set up and use.

Feature #3: Universal Binary

You've got a brand new MacBook Pro: now what pro software are you gonna run on it? Unity, of course. Unity 1.5 is now a fully universal application – so you can make your games even faster than before.

We've been testing Universal Unity for the past months, so we know it'll fry you with its speed-induced heat.

Feature #4: High-speed Car Physics

Ever wanted to drive at insane speeds? Now you can get that off your chest by making your very own racing game. For Unity 1.5 we've added a dedicated wheel collider that accurately simulates the traction model of real cars.

It has never been so easy to create racing games, or for that matter cool mountable vehicles for your first person shooters.Wheel Collider docs

Feature #5: More Full-Screen Filters!

We added another batch of filters to really make your Unity games shine. Use the Noise Filter to get a grainy black-white look (complete with hair on the film stock). Make your sci-fi worlds live in vivid colors using the Glow Filter. Or give life to your horror game with the dynamic Contrast Stretch. This is a Unity Pro feature.

Feature #6: Mesh Script Interface

In Unity 1.5 you have full access to all vertex data / normals / tangents / colors / UVs and triangles.

Generate infinite terrains, deform objects, break or merge objects. The interface is simple, and ridiculously fast too: we measured 1,200,000 vertices processed per second. With JavaScript!Mesh documentation

Feature #7: Textures Script Interface

Generate or modify textures on the fly. Or use textures as source data for anything (generate terrains from heightmaps, analyze image colors, ...).Texture2D documentation

Feature #8: Particle Script Interface

The last entry in Unity's new full control programme is a fully exposed particle interface. You can now manually spawn particles and give them arbitrary position, velocity, size, and color. You can loop through all existing particles and animate them from a script, adding or removing particles you want.ParticleEmitter documentation

Feature #9: Lightmap Support

Now lightmaps are fully supported. Bake the light in your 3D app of choice, then import painlessly into Unity for that contrastful look.

Feature #10: TrueType Typography

Just drag any TrueType font (.ttf) into the project. Create a GUI Text or Text Mesh and drag the imported font onto the font property.

Feature #11: Cinema 4D Importer

Cinema 4D files are now imported natively. If Cinema 4D is not already running Unity will launch it and automatically install a converter plug-in. The whole process is completely seamless, just drop your .c4d files into the project.

Feature #12: Documentation & Tutorials

We now have 5x as much documentation as before. Everything has been read, reread, corrected and polished. All components now have annotated screenshots. Thanks to Sam Kalman for helping us out on this project.

Unity 1.5 also includes five tutorials covering a wide range of topics.

After all, what good is the world's best tool if you can't figure out how to use it?Documentation & Tutorials

Other New Features

In addition to the above Unity 1.5 includes more than 256 new small features, improvements. Here are most of these.

Graphics

  • Fullscreen AntiAliasing and Sync to vertical retrace (Set it up in Edit -> Quality Settings)
  • Improved texture compression quality and speed. We also now support DXTC5 texture compression which is better for textures with compressed alpha.
  • Water cleanup/additions:
    • Water prefab now reflects the skybox
    • Wave speed is now independent of wave scale
    • Made property names clearer
    • Added reflective & refractive water in Unity Pro
    • Optimized the shaders
  • Pro Standard Assets:
    • Added reflective & refractive water
    • Optimized all water shaders, made property names clearer
    • Added Glow, Noise and Contrast Stretch image effects
    • Glow uses extra brightness from alpha channel, you may want to set main color of your materials to use zero alpha
    • Blur image effect more efficient at doing large blurs
    • Edge Detect effect now uses a different and faster filter
    • Image effects now no longer print "no subshaders..." warning on old video cards
  • Builtin shaders cleanup:
    • Added lightmapped shaders
    • Properly handle texture placement offset
    • Work nice with glow (put extra brightness into alpha, i.e. specular highlights)
    • Diffuse shader is now truly per-pixel, so you can have bright lights near big polygons
    • There is a Diffuse (fast) shader which does the same as the old diffuse
    • DiffuseDetail now does a proper detail texture (i.e. gray texture has no effect)
    • Most of the shaders are faster
    • Skybox shaders use background render-queue
  • Added light culling mask. This allows you to selectively apply lights to only some objects
  • GUILayer now renders after all image effects
  • Shaderlab now supports Fallback off statement, which won't complain if no subshaders can run
  • ShaderLab now uses the Cg 1.4.1 compiler

Scripting

  • When calling a coroutine from JavaScript it will automatically be started. Thus it's no longer necessary to use StartCoroutine. In C# you still have to do this
  • Added an Array class to JavaScript which behaves exactly like ECMA 1.5 standard JavaScript.
  • Improved dynamic typing in JavaScript
  • Renamed FileTexture to Texture2D
  • Renderers can now be made invisible: Use renderer.enabled = false;
  • Added Animation WrapMode.ClampForever, this is very useful with additive animation blending
  • Added GameObject.CreatePrimitive() function for creating primitives from code
  • A Material's texture placement (offset & scale) can be set from scripts
  • Added a SendMessageUpwards() function
  • Fog and ambient lighting settings are now exposed to the script interface. Use RenderSettings.fogColor = Color.white;
  • GetComponent() can now also be used with a string. This is useful for accessing scripts written in other languages
  • Added AddExplosionForce() and ClosestPointToBounds() function to rigidbody
  • Scripting access to make rigidbodies sleep and solver iteration count:
    • Sleep minimum velocity can be overridden per rigidbody.
    • Rigidbody.Sleep() can force a rigidbody to start sleeping

Physics

  • Rigidbody interpolation. This is an extremely important feature if your main character or vehicle is a Rigidbody. This will remove any stuttering on the Rigidbody, which is most visible when you have a camera following it. For non-player Rigidbodies, there is no need to use interpolation as it doesn't make any visible difference and comes at a tiny performance cost
  • Improved CharacterController stability. You can now use the CharacterController from inside the Update() function too. Movement also appears smooth now

Runtime

  • Joystick improvements: Unity now contains an XML file for overriding reported joystick minimum and maximum values (Saitek joysticks report skewed min and max values). If you have a joystick that doesn't work correctly please try adjusting the XML file and send back the results so we can ship them to all Unity users
  • Improved multi-monitor support. When going fullscreen, Unity will now choose the monitor that the screenselector was placed in
  • Alt-Enter now toggles fullscreen mode in standalone Windows players
  • Project Settings now have an option to always display the Unity watermark

Performance

  • Quality Settings made much more flexible. They allows you to associate graphics quality settings to the ScreenSelectors quality setting
  • Using skyboxes is much faster now (does depth clear in hw-friendly way)
  • Editor performance optimizations in high object count scenes with a lot of gizmos
  • Up 300% performance improvement when rendering skinned meshes. You can selected the number of weights used per bone (1, 2 or 4). It is also possible to select the accuracy used when transforming normals. If your mesh is not scaled, Fast will look just as good as Accurate but take up much less processing power
  • 300% performance improvement for rendering of high poly count meshes on Windows
  • By default imported skinned meshes are now set to only process if visible. This implies that the bounding box will not change after it has been built the first time. If you are not animating a character but for example a big crane and you see the object popping into view too late, disableonly update if visible.

Editor

  • Greatly improved editor grid rendering
  • Added Layers menu to Scene View
  • Renamed inspector expert mode to debug
  • Renamed LightManager to Render Settings
  • Renamed ProjectSettings to Player Settings
  • Performance optimizations when entering playmode in the editor
  • Improved null reference exception messages. When encountering exceptions, Unity will now display much more readable warnings about what has gone wrong:
      UnassignedReferenceException: The variable target of SuperMarioCamera has not been assigned. This happened in the game object "Main Camera".
      You probably need to select the "Main Camera" in the hierarchy and assign the target variable of the SuperMarioCamera script in the inspector.

Asset importing

  • Support for Collada 1.4 files
  • Support for importing .dxf and .obj files
  • Added Collada based Blender importer. This fixes several bugs in the handling of rotations and pivot points (some Blender files would import rotations incorrectly). While this version doesn't add any new features, it will allow importing animations once the Collada exporter for Blender supports it. At the moment it supports importing UVs, normals, and vertices. This importer is more streamlined and requires Blender version 2.4. If you have a Blender file that was already imported with an earlier version of Unity, in order to stay consistent with the old imported file the new Blender importer will not be used. To use the new importer simply duplicate the Blender file in the Finder.
  • Unity packages (.unitypackage) can now be opened with a double click in the Finder
  • The default global scale when importing .fbx files directly is now 0.01 instead of 1.0. This fits how most modelers except Maya work.
  • Worked around several issues in the Lightwave .fbx exporter when exporting meshes with assigned textures. You can now assign multiple textures to the same mesh in Lightwave and it will import correctly into Unity

Text and GUI

  • Added GUI Text pixelOffset
  • Added a Create 3D Text menu command. This will create a complete Text Mesh. Selecting a font asset before fist will assign that font to the created Text Mesh
  • GameObject -> Create -> GuiTexture now creates a GUI Texture with the size of the texture that will maintain its pixel size regardless of resolution

Bug-fixes and polish

  • Audio Listener added to FPS camera prefab in standard assets
  • Unity now works around an issue with a new version of the (now broken) Quicktime LiveType.component
  • When playing an animation and it is the last active animation, it will clamp to the last frame instead of just stopping before the frame

  • Worked around OpenGL driver bug on Geforce FX 5200 cards using PowerOfTwo Render Textures
  • On Windows, three argument texture combiners (a*b+c, a*b+-c) now work on nVidia cards
  • Worked around an Apple OpenAL crashbug when playing streaming Ogg Vorbis sounds. The workaround simply preloads the whole Ogg Vorbis instead of streaming it. We are pushing Apple to fix this issue, so that we can enable streaming Ogg Vorbis sounds again
  • Tool handle doesn't wiggle anymore when a particle system is selected

Unity 1.5.1

When making middleware for such a wide audience as we do, one of the challenges is that many of the end users of our customer's games have outdated hardware and graphics drivers. The solution? We've spent massive resources testing our runtime on these platforms. Thus, we're proud to announce Unity 1.5.1, with rock-solid support for a terrifying range of old hardware/software combinations.

Major New Features

Feature #1: Support for old hardware and drivers

When making middleware for such a wide audience as we do, one of the challenges is that many of the end users of our customer's games have outdated hardware and graphics drivers. Some of these drivers are awfully broken, and functionality that is documented to work, doesn't. The solution? We've spent massive resources testing our runtime on these platforms and working around driver bugs. Thus, we're proud to announce Unity 1.5.1, with rock-solid supports for a terrifying range of old hardware/software combinations.

While not the sexiest of "features", the benefits are massive: reduced support costs, reduced quality assurance, and increased market reach. The result is that you have more time to make a great game. This is critical to anyone who wants to make games for a wide casual audience.

Feature #2: Unicode Support

Unity finally supports Unicode for game localization. Japanese? Chinese? Korean? Not only westerners play games.

Unicode TrueType fonts now import correctly and it is possible to enter Unicode characters into strings in the inspector. Scripts can even be saved in the UTF16 encoding which allows them to contain complete Unicode strings.

Feature #3: Car Wizard

Unity 1.5 brought high-speed physical modelling of vehicles, with suspension, tires and that whole racing-thing. With Unity 1.5.1 it's become really easy with a new "car wizard". Drag in a car model, run the wizard, set your parameters, drive.

But don't let the buzzwords scare you – it's still easy to set up and use. A web player The Race demo project

New Example Project #1: 3D Platform Game

Want to make a 3D platformer in the style of "Super Mario 64", complete with jump-pads, feel-good camera controls, and a cute (or scary) animated character? This example project has scripts to control such a game. Loads of goodies include: scripts, 3D objects and rigged character complete with textures and animations.

As always, the assets from the example projects can be used free of charge commercially (and well as non-). The scripts are well written and can be extended and repurposed. 3D Platform Game project

New Example Project #2: Nature Rendering

To help you create gorgeous terrains with foliage such as animated grass and trees, we added this example project. It includes several really cool parts: A grass generator script to dynamically generate leaves of grass across a terrain mesh, foliage and terrain shaders, and two fully textured sample trees.

As always, the assets from the example projects can be used free of charge commercially (and well as non-). The scripts are well written and can be extended and repurposed. A web player The Nature Rendering project

All-Round Improvements

We weren't relaxing these last months. We've been hard at work responding to your suggestions and improving Unity back to back. Unity supports native importing of files from the newly released packages, Maya 8 and Cinema 4D 9.0 + 9.1, and improves the native support for complex hierarchies in Blender.

Unity 1.5.1 has also been optimized. Complex scenes render 15% faster, and a new script has been added to combine objects, which can provide for massively increased rendering speeds.

Ogg Vorbis playback improved

  • Improved playback of very short Ogg Vorbis clips on Intel Macs and Windows.
  • Enabled Ogg Vorbis streaming on Intel Macs on OS X 10.4.7+, because Apple's OpenAL driver has been patched.

  • Rigidbody.useGravity will now wake up a Rigidbody when enabled.

Graphics

  • Massive improvements of graphics card and driver compatibility on Windows. We worked around a lot of broken graphics card driver bugs, including some very old ones. We have tested against most graphics cards with different driver versions. In particular:
    • Fixed rendering artifacts on most Intel cards (845, 865, 945).
    • Worked around older ATI drivers parsing vertex programs incorrectly.
    • Disabled software vertex programs on DX7-level NVIDIA and Intel cards.

    • Worked around some SiS 630/651/730 drivers falsely claiming they're OpenGL 2.0.
    • Various graphics cards have trouble when performing rendering from a separate thread (most ATI and Intel drivers). Disabled multithreaded rendering on those.
    • On some ATI drivers, the Unity Web Player could hang when getting out of full-screen.
    • Unity Web Player on Windows now grays out full-screen menu item if it is not safe to switch to full-screen mode due to buggy graphics card drivers.
  • Glow effect looks a lot nicer. Less white fringes around, finer control of glow color based on the object's color.
  • The color of a text material can now be modified and is stored when closing the project.
  • Graphics performance optimization with up to 15% faster rendering when many objects are visible.
  • Decal shader now behaves similar to VertexLit, but with a second (decal) texture.
  • Improved sorting for transparent objects. Transparent objects are now sorted by now sorted by bounding volume center instead ofTransform.position.

  • Loads much faster and doesn't leak resources on OS X.
  • It is possible to detect where the game was loaded from (both the srcValue and the absolute url) as Application.srcValue andAppliction.absoluteUrl.
  • For computers that do not have any OpenGL drivers, a warning is issued before continuing with software rendering.
  • Unity Web Player on Windows runs much faster in full-screen, and full-screen mode is entered faster.
  • Unity Web Player mouse position in Firefox now works correctly.

Deployment

  • Screen selector dialog can now be hidden by default. The new options in the player settings are:
    • Enabled by default.
    • Disabled completely.
    • Disabled by default, but shown when holding down ALT during launch.
  • Reduced mouse sensitivity on Windows to be more like on the Mac.
  • Unity games can now be run headless (without requiring a monitor), using a -batchmode command line argument (requires Unity Pro).
  • Fixed an issue with OnMouseDown when using multiple overlaid cameras and culling masks.
  • Fixed issues with keystrokes being lost and keys being stuck.

Other fixes

  • Fixed issue in package importing on network-booted setups.
