CtrlAltStudio Viewer Updated to Firestorm 4.6.7: Alpha

UPDATE: I’ve promoted this to be the recommended alpha release for Windows.

This alpha release of the CtrlAltStudio Viewer updates to the Firestorm 4.6.7 codebase and is available for people to try out. Notably, this update includes Linden Lab’s Project Interesting code, which should make loading world content significantly faster. Details of this and other changes and known issues can be found in the Firestorm release notes.

This alpha also fixes a crash some people experienced with the preceding Alpha.

Please note that this alpha still does not work with Rift direct mode and Advanced Lighting Model needs to be turned on. It is built using the 0.4.4 Rift SDK.

Viewer download:

  • Windows installer: Alpha, 18 Mar 2015.
  • Mac OSX installer: Not available at present.

      Hi Allycialee. What viewer version are you using? Does it start up? Can you log in? Does it crash when you do something in particular?

    I just noticed that Oculus SDK for PC is out… I must have missed the announcement for that in late March.

    I wonder if they have fixed the OpenGL things that were stopping direct to rift mode being tried yet… about to go on the Oculus developer forums to see if anyone has commented on that.

    The viewer works quite will with oculus looking at our opensim build. One thing however. In plain view when the avatar sits on something the lower part of the movement control changes to “Stand” and is a handy way for the user to stand. If i switch to rift view and sit the movement control no longer has “Stand” available. This makes it harder for a rift user to stand up.
    Any thoughts? Am running v1.2.3.42797 on a windows 8.

    Hi David,

    I tried it again and did only have to press Windows + right arrow key twice. Must have been sticky keys! I still couldn’t see the viewer in both sides of the Rift though. Still only the left, and when I pressed Ctrl Alt 3 nothing happened.

      Hi Peter,

      It sounds like you’re almost there …

      There’s only a 32-bit version of the viewer, and it’s suitable for running on both 32-bit and 64-bit Windows.

      Make sure that the viewer window keeps keyboard focus when you move it onto the Rift screen; i.e., press Ctrl-Alt-3 straight after pressing the Windows+arrows. without clicking elsewhere. Or click on the viewer’s icon in your Windows task bar to make sure it has focus and try Ctrl-Alt-3 again.

    Hi David,

    I’ve just noticed that I’ve downloaded the CtrlAltStudio 32 bit viewer when I’m running a 64 bit system. Maybe that’s the problem. Do you have a 64 bit version.

    I did as you suggested and unticked the full screen mode and restarted the viewer. It came on taking up only the left side of the computer’s screen as predicted. I pressed Windows then right arrow key 3 times to get the viewer into the Rift (twice didn’t work for me). But then when I pressed Ctrl Alt 3 nothing happened. The viewer still only showed in the left hand side of the Rift. In the right eye I could still see the yellow desktop. My cursor was working in the viewer in the Rift but I couldn’t see the 3D button down on the right hand side of the bottom toolbar as it was out of view.

    I have successfully viewed the Rifts demo scene on my PC. I’ve also successfully downloaded and used the Second Life viewer for the Rift. The version of the runtime is 1.5 (SDK 0.4.4)

    Hi David,

    I’ve tried to view OSGrid & 2nd Life with the CtrlAltStudio viewer through the Rift but can only see the yellow desktop with the Rift, even though I can see the double vision Rift mode view on the PC screen. I’m running the Rift in extended mode + I’ve made the changes to the preferences menu in the viewer as you recommended. Any suggestions?


    1. David Rowe Post author

      Hi Peter. You can see the twin barrel images on your PC screen OK? What you need to do is, before entering Riftlook, move the viewer window onto your Rift screen, then enter Riftlook. … On Windows this is most easily done by using the Windows + arrow-key twice, then pressing Ctrl-Alt-3.

      1. Peter Clark

        Hi David, Do you mean press the Windows key and the up-arrow key at the same time, or something else? I’ve tried a few combinations and can’t get it to work.

        1. David Rowe Post author

          Hi. Press the Windows key and either the left or right arrow key at the same time, depending on which side of your monitor you have the Rift configured in the Windows desktop. … This key combination moves the window that currently has focus to the left/right half of the screen, then another press moves it onto the next screen in that direction. (Easier than dragging with a mouse.) … Once the viewer window is on the Rift’s screen, Ctrl+Alt+3 will maximize the window and enter Riftlook.

          1. David Rowe Post author

            Make sure that you don’t have the viewer configured to run full screen: Viewer > Preferences > Graphics > Fullscreen Mode should not be ticked. (Restart required after un-ticking.)

            Then with the viewer in a window, does Window + right-arrow make the viewer window change to be a full height window on the right side of your screen? If so, and if the Rift is configured to extend the desktop to the HMD, you should be able to Window + right-arrow the viewer window onto it.

            If this doesn’t work, can you successfully view the Rift’s demo scene? (Oculus Configuration Utility > Show Demo Scene button.)

            Also, what version of the Oculus runtime do you have installed? (Oculus Configuration Utility > Help > About, lists the version and SDK of the Oculus Configuration Utility, e.g., “Version 1.5 (SDK 0.4.4)”).

    Wonderful as ever! Excellent work.
    Great to hear your working with high fidelity
    as well. The metaverse seems like it is in very
    good hands.
    Thanks again man.

    I’m a blogger and its key to set your graphics on ultra to take a nice picture, it was working just fine but with this new update everytime you set it to ultra and take a picture it crashes.. help

    1. David Rowe Post author

      Hi Ramona. I’m sorry to hear about the crashes you’re encountering taking photos!

      I haven’t managed to reproduce similar crashes. Please could you send me your program log file? C:\Users\<username>\AppData\Roaming\CtrlAltStudio Viewer\logs\CASviewer.log. Also a screen snap or text of the crash message if a dialog box is displayed when it crashes?

      Thanks very much.

    This one is also working great for me. Also AMD have released the Catalyst 15.3 beta drivers which seem to fix the rigged mesh issues that developed post-Catalyst 14.4 so maybe we don’t need the fix now unless it optimises SL better for modern OpenGL.

  12. Ollie

    I had one problem…

    I used the official SL viewer and it refuses to see my graphics card so I can’t use the Rift with it… yours works great BUT when I go into Rift mode while live streaming/recording the stream just locks so I have to refresh the stream for it to see the new mode change…

    When I do that CTRL ALT Studio flips out has a mad 5 minutes then changes it’s mode back to normal… any tips on what I can do? I have a whole show lined up and now it looks like I can’t film it (and I have about 10K people waiting for it!)

    1. David Rowe Post author

      Unfortunately I don’t have any experience in recording viewer video. What I can tell you though is that when you press Ctrl-Alt-3 to enter Riftlook view mode the code does two things: 1) makes the viewer fullscreen; 2) switches to using the Oculus display driver to render the distorted barrel images to the screen. One thing you might like to try is to run the viewer fullscreen to start with, in case this helps.

    hi,compliments this version work well.i have a question.the last version (with the crash) ,i have saw,have set the badwith to 600 kbps of default.this have set 500 of deafault.i wanna know what change raising or lowering the bandwith?and one last.not there the lag meter in this version?thanks a lot

    1. David Rowe Post author

      Hi. I’m glad you’re up and running.

      For recommendations on bandwidth setting, see: http://wiki.phoenixviewer.com/fs_speedtest

      For lag meter, you mean the statistics window? … Either click on the little twin bar graphs at the very right of the top menu bar, or enable the Advanced Menu (Avatar > Preferences > Advanced > Show Advanced Menu) then you’ll find it as Advanced > Performance Tools > Statistics Bar.

      1. ross

        ok understand.i have set the bandwith to 1000 kbps,i have a dls.yes i have saw scene load statics,but is different from lag meter.don’t understand it

        1. David Rowe Post author

          Ah, OK … Unfortunately the lag meter which was available as Avatar > Avatar Health > Lag Meter is not present in this viewer release (which is based on Firestorm 4.6.7). See the following Firestorm JIRA: http://jira.phoenixviewer.com/browse/FIRE-14314 … The lag meter will be added back in Firestorm 4.7.0 and then this viewer when and if it updates to the updated Firestorm codebase.
