Local Chat HMD Display Updated

I’ve updated the local chat script to display in a movable, resizable window on the HUD overlay when using an HMD. In desktop mode, the chat window can still be dragged outside the Interface window.

Oculus CV1 Support?

Hi! I’ve been flat out busy; everything seems to happen at once. On the Oculus Rift front I haven’t received my CV1 yet and I’m waiting for updated news on Linden Lab’s Rift project viewer. Linden Lab are working on it but I’ve not heard any inklings of when an update with CV1 support might be released.

Long term, Linden Lab’s Rift code is the correct code to include in third party viewers; mine was just a rough stop-gap measure to satisfy immediate desires to experience Second Life and OpenSim in virtual reality. And stereoscopic 3D support should be able to be added into a viewer, taking advantage of the Lab’s Rift code stereo capabilities.

In theory, even though it’s significantly out of date compared with other viewers, the current CtrlAltStudio Viewer code could be updated to SDK 1.3 to support the CV1. I’d love to do this but really have very limited time, and there are significant changes from SDK 0.6–0.8 to 1.3. So right now I’m waiting for more news on the Lab’s Rift project viewer and my CV1.

UPDATE, 11 Apr 2016: From Friday 8 April’s Third Party Viewer meeting courtesy of Inara Pey: Linden Lab are actively working on their Rift project viewer. Some things are still not working but they hope to have an update soon. They are committed to getting it working, with the latest SDK and CV1 support. See the meeting video starting at 6:57.

UPDATE, 22 May 2016: From Friday 20 May’s Third Party Viewer Meeting courtesy of Inara Pey:

Testing of the updated viewer is being carried out. There are still “a few” issues to be resolved, and it is hoped that the update will be available (still as a project viewer) in a couple of weeks.

See the meeting video starting at 2:08.

UPDATE, 3 Jul 2016: Linden Lab have released an update to their Oculus Rift viewer. This is great news! More information:

Local Chat Updated to Use Messages Object

I’ve updated the local chat script to use High Fidelity’s “Messages” object for communications instead of using an external Web server application. As before, chat windows are displayed in both desktop and HMD views. The primary user-visible difference is that chat history from the last 30 minutes is no longer displayed when you log in or visit a domain.

CtrlAltStudio Viewer Updated to Oculus SDK 0.6:

I’ve updated the CtrlAltStudio Viewer to the Rift SDK 0.6, ready for people to try out. I’m not promoting it as a recommended release until it’s had some user testing, though.

Changes of note:

  • Works in both direct and extended Rift display modes. If using extended mode you no longer need to drag the viewer onto the Rift’s screen before toggling into Riftlook view.
  • Advanced Lighting Model no longer needs to be enabled in order for Riftlook to work.
  • The hardware cursor used in previous versions has been replaced with a basic crosshair software cursor. It may not look pretty but it should still work as before.
  • There’s a new “Mirror Rift display to desktop” option in Preferences > Graphics > Display Output.
  • If you install over the top of a previous version you’ll probably want to press the “Reset” button for the “UI depth” Display Output option.

Note that if you switch between direct and extended Rift display modes, you’ll need to restart the Oculus Configuration Utility and the Oculus VR Runtime Service. To restart the Oculus Configuration Utility, right-click the utility’s tray icon and select “Exit”, and start it again from the Windows Start menu. To restart the service, find it in Windows’ Administrative Tools > Services. Or you can reboot your PC.

More details in the Release Notes.

I can achieve a pretty smooth 75 FPS experience on the Rift if the scene’s not too complex, though only if I have my main monitor set to 120Hz. If I set it to 60Hz I only get a somewhat juddery 65 FPS on the Rift. I haven’t looked into this yet and am keen to hear how other people get on. Note: You can use Ctrl+Shift+1 to display a statistics window in Riftlook.

  • Windows installer: Alpha, 3 Oct 2015.
  • Mac OSX installer: Not available.

CtrlAltStudio Viewer Plans 2015 – 2016

I developed CtrlAltStudio Viewer as a stop-gap measure to satisfy immediate desires to experience Second Life and OpenSim in virtual reality: stereoscopic 3D was implemented while waiting for the Rift DK1 to be delivered; then DK1 and DK2 support each added when they arrived. Always with the expectation that CtrlAltStudio Viewer will be abandoned when Linden Lab finish their Rift support and other third-party viewers incorporate it.

It’s been quite a long “stop-gap”; much longer than expected! But at last there’s hope that the consumer CV1 Rift will finally be delivered, sometime in Q1 2016. Before that, a Rift SDK 1.0 version is due in December this year. Hopefully, Linden Lab will finish off their Rift support promptly for CV1 when it’s available so that their code can be adopted by other TPVs. Development of CtrlAltStudio Viewer will stop at that time.

In the meantime, I am trying to find time to keep CtrlAltStudio Viewer somewhat up to date. Unfortunately, time is in short supply for me these days. However, I have the code working with SDK 0.6 in direct mode with a basic software cursor. (There’s no hardware cursor in direct mode.) I have a few issues to sort out and will release an alpha as soon as possible, “as is”, to see how people find it. Not polished but should be usable.

After that, I may update to a more recent Firestorm codebase, or perhaps update to SDK 0.7 or even SDK 1.0. It just depends on Oculus and Firestorm updates, people’s needs, and my time availability.

Local Chat for High Fidelity UI Reworked

I’ve reworked the local chat script to display in its own window in desktop mode.


This window can be dragged outside the Interface window and can be resized. As well as being more readable, you can past text into the input pane and copy test from the chat history.

When in HMD display mode, the chat is displayed in an HUD window as before.

The script URL remains the same: http://ctrlaltstudio.com/downloads/hifi/scripts/chat.js

Note: You may need to do a “Reload” in the Running Scripts window to refresh your cached copy.


  • 15 Aug 2015: Made the size and position of the chat window be remembered between program runs.
  • 8 Aug 2015: Fixed chat messages not being displayed when script loads.
