Kokua- is available. Update: Downloads now have Windlight settings.

Downloads are updated with Windlight settings
The code base is up to date with Linden Lab (LL) viewer-release 3.4.5.
Viewer animation override (AO) has been ported from Teapot and Firestorm viewers. Thanks to Tank Master for some firestorm smoke lifting and Key Gruin, Marcus Llewellyn, and Nebadon from OsGrid for testing. For those interested in additional information about use of the AO; there an excellent you tube video class from Firestorm here.

We have added to the grid selection default drop down list the following:
Island Oasis http://www.islandoasis.biz/
Virtual Highway http://virtualhighway.us/vhweb/
VIRT you http://virtyou.com/en/

    Hey the Linux 32 seems to be corrupted, it will not unzip for me.

  2. NickyP

    Thanks, Ill check it out.

    You may have downloaded while I was in process of uploading new files over the old file. I downloaded and extracted under ubuntu 12.04. Then, started the viewer and logged on.

    I setup Kokua on my computer but experience bad lag that i wasn’t getting with Imprudence and also took ages for my avatar to rez.

    So far so good connecting to my own grid running OS 0.7.5! A few little quirks though, but nothing too bad. Overall, super awesome job. I’ll be switching over to Kokua now and reccomending it as the default for my grid (once I get around to setting up the web end of things). :)

    For reference, my hardware specs are as follows:

    The friends tab on the People window didn’t propigate right away. I couldn’t figure out why until I went to find something in my inventory. After my inventory loaded my friends list suddenly popped in.

    The default graphics settings things were a little bit laggy and the whole scene was white washed from the different light sources I had put in years ago. After tweaking a few things the lag went away and after unticking “Lights and Shadows” the white wash went away. I’m guessing this is likely due to the old old lights that I have in my scene which should be redone, however strangely enough I didn’t have that problem on Imprudence or the OpenSim version of Firestorm – so I’m not sure if those were already tweaked down somewhere? (If needed you can test this scene for yourself, just hypergrid over to grid.pseudospace.net:8002:ellis island)

    Help -> About Kokua took an awefully long time to come up, and at first I thought it had crashed the viewer. After about 45 seconds, it finally came up and things settled back down.

    Avatar -> Account Dashboard still points to Second Life’s website.

    Help -> Howto brings up a white window that states “AccessDeniedAccess”

    Camera Controls window seems to take quite a bit of screen real estate and cannot be sized down.

    People window doesn’t remain open after shutting down then restarting the viewer.

    the latest 3 builds have not been working on openSUSE 12.2 64 bit (in the same configuration, everything worked well and all other clients work well also). the client simply refuses to start. These are the errors i get:

    (do-not-directly-run-kokua-bin:17497): GLib-WARNING **: unknown option bit(s) set

    (do-not-directly-run-kokua-bin:17497): GLib-CRITICAL **: g_regex_match_full: assertion `regex != NULL’ failed

    (do-not-directly-run-kokua-bin:17497): GLib-CRITICAL **: g_match_info_get_match_count: assertion `match_info’ failed

    (do-not-directly-run-kokua-bin:17497): GLib-CRITICAL **: g_regex_unref: assertion `regex != NULL’ failed

    and this set of errors appear repeatedly for about 10-15 times. What could be the issue?

  7. NickyP

    Thanks for testing Kokua and commenting.
    I don’t have SUSE to test with. Maybe another user of SUSE can help out. Also, there have been some reported problem using Oxygen / KDE with many viewers including LL viewer. If earlier builds work at what version was it last working.

  8. o2

    Kokua- was working
    and by the way, i love this viewer!

  9. NickyP

    “Kokua- was working”
    We need to work out that it is a for sure viewer change and not a distro update/upgrade that caused this. I know it is bit of a hassle but, if you haven’t already could you reinstall the older versions and see
    if they still work?
    25633 is here.

  10. o2

    now i see, that version of kokua also doesn’t work, and neither does 3.4.3. however, i see the official sl client 3.4.5 is working, so do the latest versions of dolphin and firestorm… and the latest version of kokua 32 bit is also working.

  11. NickyP

    Are you using the Oxygen+gtk theme? If so, can you try a different theme? Singularity offers a 64 bit v1+++++++ viewer. But, at last report, it is also failing on Oxygen+gtk theme.

  12. o2

    Using KDE 4.10 with oxygen theme, and for gtk style applications, oxygen+gtk theme was selected, so i changed it and.. magic! kokua works :) thanks, nicky! only, now i see media plugin webkit error, but that can be solved it seems with a bit of tweaking :)

  13. Ci Sense

    I am very pleased to see Kokua finally working on my 32bit XP 32 system despite its Radeon graphic card. Video capture performance is looking good enough for machinima, not quite Imprudence speed but hey mesh is mesh.

    Great work!

    ps Cataylst 12.1 is the only driver that works without crashing

  14. Mich

    Awesome Linux 64bit running really good it seems, everything plays including audio stream, little bit of trouble viewing the streaming video on web-prims but other than that seems stable!

  15. NickyP

    Thanks for using Kokua and taking time to comment. Please use this redmine task to record your media successes and/or failures and review what others users have found.

    For some reason on my system running Xubuntu 12.10 x64, the x64 Linux version is far slower than the x86 one. I get more than double the frame rate in the x86 version.

  17. NickyP

    Thanks for the feedback. I only have linux in virtual machine so, I can’t evaluate. Maybe some other Xubuntu users can comment. Are you properly set up for multi-arch?

  18. Koli

    ia32-libs and ia32-libs-multiarch are installed, though that shouldn’t really affect the 64-bit viewer’s performance.

  19. Jean Horten

    I am getting very very poor frame rates with Kokua linux 64 bit, approx 80% less than on other 64 bit Linux viewers. This makes Kokua unuseable for me

  20. NickyP

    Is this with the inventory full loaded and all textures rezzed? Kokua has its own settings folder and if you switch from another viewer with its fully populated cache and don’t allow Kokua settle then, it will have low frame rates. In a previous comment is report of 32 bit Kokua running on 64 bit Xbuntu having a higher frame rate than the 64 bit version. If you can send via email a test grid/region to me nickyperianyahoo.com I will visit and test there.

  21. Jean Horten

    The low fps rates occur everywhere, with all Kokua V3.4.x and 3.5.x 64 bit Linux versions. I alwways delete the cache folder and let the viewer idle for 30 minutes before looking at the fps when I make FPS comparisons between different viewers.
    OS: Linux Mint 14 MATE 64 bit, Kernel 3.8.0, CPU: AMD FX 8150, 16 GB RAM, GPU: nVidia 580 GTX 3GB, driver: nVidia 313.26.
    Kokua 64 bit: 5-10 FPS, Ll V 3.5.x 32 bit: 10-15 fps, Firestorm 32 bit 20-30 FPS, Singularity 64 bit 40-80 FPS, all tested in maxed out graphics settings (Ultra)

  22. NickyP

    Based on yours and another comment about performance I found the the 64 bit builds did not have compiler optimization. Please give this a try and see if you see improvement.

  23. Orion Pseudo

    WOW! Thats a massive improvement! On the standard 3.5.1 linux 64 I was averaging about 25 to 30fps which I figured was just due to my sim being overly primmy. With the optimized I’m getting a minimum of 37 with a max of 45fps on that same sim. Hi5 good job. :)
