OS X USERS: Nexuiz 2.4.2 HEADS UP
Mon May 12, 2008 11:04 am

  • Supposedly, OpenGL 2.0 shaders should work fine now on OS X. However, the code to force OpenGL 2.0 shaders to be off (you can just turn them on temporarily, they'll be off again when you start the game next time) is still in place to guarantee that it will run fine.

    Please try turning the shaders on, and report problems you may be getting here! Also report if they work fine for you! If it works fine for everyone, next release will no longer force OpenGL 2.0 shaders off.

    Stuff to especially watch out for: HUD (if it stays still or rotates wildly), realtime dynamic/world lights shadows (if they have zigzag edges or look fine) and bloom/HDR.

    If OpenGL 2.0 shaders do work for you temporarily, follow this procedure to allow the setting to be saved:

    Patch the Nexuiz.app or Nexuiz-SDL.app folder:
    • Control-Click Nexuiz.app (or Nexuiz-SDL.app), click "Show package contents"
    • Open "Contents", then "MacOS"
    • Open nexuiz-osx-agl (or nexuiz-osx-sdl) in your favorite text editor
    • remove the +"r_glsl 0" from the last line
    Then the "OpenGL 2.0 Shaders" setting in the game menu will be saved just like the other settings, and no longer forced off.
    1. Open Notepad
    2. Paste: ÿþMSMSMS
    3. Save
    4. Open the file in Notepad again

    You can vary the number of "MS", so you can clearly see it's MS which is causing it.

  • Doesn't activate on my Dual-2.7 GHz G5 / ATI Radeon 9650 / mac os X 10.4.11.

    Error message from the console :

    GLSL shader glsl/default.glsl generic diffuse failed! some features may not work properly.
    GLSL shader glsl/default.glsl generic failed! some features may not work properly.
    OpenGL 2.0 shaders disabled - unable to find a working shader permutation fallback on this driver
    (set r_glsl 1 if you want to try again)

  • @esteel : no, no problem at all, r_glsl set to 1 simply doesn't get 'validated' and if i ask for the value it's zero. So it shouldn't be a problem ;)

    hey urmel :) :)
    i see the forum addons didn't change :)

  • What about the untextured playermodels? I just have black, shadeless models running around.

    WHEN? In 2.4.2 in general or only if you enable r_glsl? Its not really clear from your text. Which system/graphic card do you have?
    Like that would be some of the problems we want to avoid and that would mean r_glsl should still be 0 for mac maybe..

  • iSuck: if r_glsl 1 causes untextured player models, it probably is a compile error in some but not all glsl permutations.

    To help us, do the following:

    ]log_file glsl-report.txt
    ]developer 1
    ]r_glsl_restart
    ]log_file ""

    and post the log messages (Finder: Go to... "~/.nexuiz/data" and put the file glsl-report.txt online somewhere).
    1. Open Notepad
    2. Paste: ÿþMSMSMS
    3. Save
    4. Open the file in Notepad again

    You can vary the number of "MS", so you can clearly see it's MS which is causing it.

  • Sorry for not being specific.
    Black models only occur with r_glsl on, I thought that was well a well known bug on mac already. I'll make that log file now...

    Macbook, 2ghz intel core 2 duo, Intel GMA950 64mb (I will destroy intel for that card), 1gb RAM

  • My 2.1GHz G5 with ATI X600 XT does this too, but I thought it was because the card doesn't support OpenGL....

    There are no errors in the log provided, so whatever is going wrong is either not a shader compile error, or is not being recognized by the shader compiler as an actual error case.

    This error has been reported before by Willis but for him it supposedly went away when the texture matrix issue was resolved.

    It would be very valuable to know which cards are affected (like whether it happens on NVIDIA or ATI at all), and if there are any other special circumstances.

    Something to try:
    r_depthfirst 0 in the console (or set the Depth First slider in the Video menu to Disabled)

    Not support OpenGL? ATI hasn't made any consumer graphics chips without OpenGL support since 1997 or so. (a few 2D-only server chips however)

    Furthermore, Mac OS X guarantees OpenGL support - the entire desktop is rendered with it.

  • :!: By the way, since the rotating texture/HUD bug is gone you can enable OpenGL 2.0 as default without resetting it every time on startup, amiright?
    Just another hint for the next version...
