This Viewer is No Longer Being Maintained
The CtrlAltStudio Viewer was developed in order to try out and share a number of ideas, primarily Oculus Rift support and stereoscopic 3D display, but also variable walk & fly speed, Xbox 360 controller support, and Kinect for Windows control. It is based on the Firestorm Viewer and can be used with both OpenSim and Second Life.
Oculus CV1 is not supported. For the latest on this, see: Oculus CV1 Support?
Linden Lab’s cashier update of 15 Jun 2016 is not supported. This means that you can no longer perform L$ transactions with this viewer.
This viewer is no longer being maintained. The most recent Windows release is based on Firestorm 4.6.9 which was released in Dec 2014; there have been many improvements in Firestorm and other viewers since then that are not included in CtrlAltStudio Viewer. Unless you really need Oculus DK1/DK2 or stereoscopic 3D support you should seriously consider using another viewer instead: either Linden Lab’s viewer or one of the other third party viewers such as Firestorm.
Latest Windows release

- Mac OSX installer: Not available
Latest OSX release
- Windows installer: 126.96.36.199224 Alpha 5, 12 Dec 2014.
- Mac OSX installer: 188.8.131.52224 Alpha 5, 12 Dec 2014.
Based on Firestorm 4.6.5. Built using Oculus Rift SDK 0.4.4.
This enables you to have a look around in Second Life and OpenSim with your Oculus Rift headset. Some UI capability is provided.
Use the viewer as normal to get to where you want to go, then move the viewer window onto your Rift display (e.g., Windows key plus arrow key twice), toggle into “Riftlook” mode (Ctrl-Alt-3), and don your Rift headset. Move your head to look around and use the arrow or WASD keys to move about.
Setup and Usage:
- Oculus Runtime downloaded from https://developer.oculusvr.com/and installed.
- Oculus Configuration Utility used to update your DK2’s firmare if necessary.
- Oculus Configuration Utility used to measure your inter-pupillary distance.
- Rift Display Mode set to “Extend Desktop to the HMD”.
- Windows displays configured to have the Rift display extend the desktop and display in landscape orientation. Note: Orientations shown in Windows Control Panel and NVIDIA Control Panel may differ.
- Viewer configured to be in windowed mode, i.e., make sure Preferences > Graphics > General > Fullscreen mode is not ticked.
- Advanced Lighting Model turned on: Preferences > Graphics > General > Advanced Lighting Model.
- Oculus Rift output turned on: Preferences > Graphics > Display Output > Oculus Rift. And restart the viewer.
- Also recommended is turning Antialiasing on: Preferences > Graphics > Hardware Settings.
- Start the viewer and move your viewer window into your Rift display: drag it, or on Windows use the Windows key + arrow key twice.
- Ctrl+Alt+3 then makes the window fullscreen and switches into Riftlook view.
- Dismiss the health & safety warning by pressing a key. (It will go away after a few seconds. This “feature” is built into the Rift display driver and cannot be easily altered at present. It does go away automatically after a couple of seconds the second and subsequent times you toggle into Riftlook.)
- To “zero” your orientation and positional tracking location press Ctrl+Spacebar.
- To exit Riftlook and move the viewer window back to your main display: Ctrl-Alt-3 then Windows + left-arrow.
- To improve your frame rate, reduce your draw distance and/or turn shadows off.
- If you have good frame rates, including while turning, set your Rift display to 75Hz: Control Panel > Display > Screen Resolution > Advanced Settings > Monitor.
- If you’re experiencing judder while turning then try to try disabling one or more of the “Dynamic prediction” … “Pixel overdrive” Oculus Rift options, consider configuring your Rift display to 60Hz, and possibly try enabling triple buffering in your display driver.
- If you have a stereoscopic 3D system, you may need to disable stereoscopic 3D display in order to stop the Rift’s display rate being reduced from 75Hz to 60Hz. [Estelle Pienaar]
- If you have an NVIDIA graphics card, adding an entry for the viewer in the NVIDIA Control Panel 3D Settings and setting the preferred refresh rate to unlimited may let your Rift run at 75Hz without needing to make it your primary monitor. [Phoenix]
- Make sure you don’t have Preferences > Graphics > Rendering > Limit Framerate enabled.
- If using Windows 7 and you’re experiencing juddering, try turning off Windows 7’s Aero. [Phoenix]
- Setting your Rift to be your primary monitor may also reduce judder. [Estelle Pienaar]
- Disabling DK1 Legacy App Support in the Rift Display Mode may also reduce judder.
- If you have configured Oculus Rift output for seated operation, “forwards” is the direction your Rift was pointing when you toggled into Riftlook.
- If you have configured Oculus Rift output for standing operation, “forwards” is the direction your Rift is pointing.
- If you want to strafe instead of turn in seated operation, or turn instead of strafe if you have the “strafe” option selected, use Shift-Left and Shift-Right.
- You can use keyboard shortcuts to show and hide dialog boxes such as the Conversations window (Ctrl-T), Inventory (Ctrl-I), e.g., if you want to select a landmark to teleport to, Ctrl-Shift-M to display the minimap, etc. Keyboard shortcuts are shown beside menu items.
- To display avatar toasts in the Rift — Preferences > Chat > General > Show chat in bubbles above avatars.
- With floating text you may want to adjust the distance the floating text fades at so that distant text is not so annoying in Riftlook: Preferences > Graphics > Rendering > Floating text fades.
- You can use voice chat and toggle your microphone on/off using the middle mouse button or other key you configure in Preferences > Sound & Media > Voice Settings.
- To get into 3rd person view, depending on your “Mouse moves cursor / view” setting, either scroll out with your mousewheel or press Alt and scroll out with your mousewheel. You can then orbit around points etc. with your mouse and Ctrl, Alt, and Shift keys as usual. Press Esc to get back into 1st person view.
This uses OpenGL quad-buffered stereoscopic 3D. It works with NVIDIA GeForce and 3D Vision with driver 314.07 or later; should work with GeForce GTS250 or better. It should also work with NVIDIA Quadro cards plus AMD Radion HD 6000 or better and FireGL V7600 or better with recent drivers.
For active shutter glass display using an NVIDIA GeForce graphics card and NVIDIA 3D Vision on Windows you need:
- GeForce driver 314.07 or later.
- Graphics configured to display at 120Hz.
- Monitor configured to display at 120Hz.
- Stereoscopic 3D enabled in the NVIDIA Control Panel.
- 3D Vision set up and working. *
- Viewer configured to run full screen — Preferences > Graphics > General.
- Viewer configured for stereoscopic 3D output — Preferences > Graphics > Display Output.
Press Ctrl+Alt+3 or click the “3D” button on the toolbar to toggle stereoscopic 3D on/off.
There’s an option to set the display output to 120Hz for stereoscopic 3D. This is useful if you have shutter glasses and want to only display at 120Hz when you use the viewer.
If you have a 144Hz monitor you may need to set one or both of your graphics and monitor to 60Hz so that the 3D Vision driver automatically doubles things to 120Hz.
If you have a passive 3D display or are using a 3DTV, you don’t need to and in fact normally shouldn’t set things to 120Hz; instead, configure things per the requirements of your system.
* Note, however, that it doesn’t work with 3D Vision Discover anaglyph.
Variable Walking and Flying Speed
This enables you to walk and fly at speeds slower than normal and, if using an Xbox controller or Kinect to control movement, walk and fly at varying speeds up to your configured maximum. Works best in Second Life; works reasonably well in in OpenSim 0.8.0; in OpenSim 0.7.6, walking is always at normal speed and flying is stuttery at slower speeds.
- Configure “Walk speed” in Preferences > Move & View > Movement.
- You can also use Ctrl-PgUp and Ctrl-PgDn to increase and decrease your walk speed.
- When using an Xbox controller, speed depends on how much you move the stick.
- When using a SpaceNavigator, speed depends on how much pressure you apply to its knob.
- At slower walk speeds you may want to disable “Turn avatar around when walking backwards”.
Xbox 360 Controller
Xbox 360 controllers can be used with the following control scheme:
- Back: Toggle flycam on/off.
- Start: Toggle between moving avatar and moving cursor.
- Back + Start: Toggle Rift or 3D stereoscopic 3D on/off.
- In avatar movement mode:
- Left stick: Move forwards / backwards and left / right.
- Right stick: Change camera pitch and yaw.
- Left & right triggers: Fly down / up.
- In cursor movement mode:
- Left stick: Move cursor up / down and left / right.
- Right stick: Scroll mouse wheel forwards / backwards (i.e., zoom view).
- Left & right triggers: No action.
- Left stick click: Jump up / stop flying.
- Right stick click: Toggle 1st person view.
- Left bumper: Left or right mouse click. *
- Right bumper: Right or left mouse click. *
- Y key: Escape
- X key: Control
- A key: Alt
- B key: Shift
- D-pad: Not used * There’s a preferences option to swap bumper buttons.
Thus you can walk your avatar, fly your avatar, use mouselook, use flycam, orbit about points in 3rd person view, click on objects, and use objects’ context menus … with normal, stereoscopic 3D, or Oculus Rift display output.
With your Xbox 360 controller connected — wired or wireless — enable it in Preferences > Move & View > Movement. Then you can adjust its configuration using the associated Joystick Configuration button. Xbox 360-specific defaults are provided. You should also calibrate your controller, e.g., using the device’s properties provided via Windows’ Devices and Printers folder.
Kinect for Windows
On a Windows PC* with a Kinect for Windows sensor installed, this enables you to nominate the physical spot you are standing on to be “home”. Then you move off this spot to control the direction your avatar walks or flies, turn your shoulders to turn your avatar, and use gestures to fly up and down.
* Does not work on Mac OSX.
- Install either the Kinect runtime or the Kinect SDK.
- Enable and configure in Preferences > Move & View > Movement.
- Uses the Second Life login screen instead of the Firestorm one if logging into Second Life.
- CtrlAltStudio Viewer skin and colours.
- Minimum draw distance reduced to 8m.
- Maximum bandwidth increased to 10,000kbps.
- Rift direct mode is not supported.
- The menu bars and toolbar aren’t displayed in Riftlook.
- Right-clicking on objects in Riftlook always displays the context menu in list form rather than pie form, even if “Use Pie Menu” is configured in the preferences.
- Left- and right-clicking objects in Riftlook display works best with the cursor in the left eye’s view.
- Improper display during teleport while in Riftlook.
- Flickering objects at the edge of the Riftlook screen.
- With variable walk / fly speeds in OpenSim 0.7.6, walking is always at full speed and flying at slow speeds is stuttery.
- Variable walk / fly speeds can be a bit jerky at slower speeds, and the avatar doesn’t necessarily animate smoothly.
- Kinect for Windows control is available only when running on Windows.
- So that it can be used with both Second Life and OpenSim, this viewer is compiled without the HAVOK library. This means that certain advanced features are not available when used with Second Life: visual display of the pathfinding navmesh and rigged mesh upload support.
- No crash log reporting: Crash logs are not sent to anybody.
