    Ue4 cave demo for linux

    Hi,
    I have compiled Unreal 4 demo Cave Effects using UE4.1 final..

    I have uploaded demo here: http://www.mediafire.com/download/0r...l784m/cave.rar

    Demo runs by default using GL 3.2 profile and can be run in OGL 4.3 mode via -opengl4 argument.
    It can use other arguments similar to posted ue4 win demos here (http://www.techpowerup.com/downloads...l-tech-demo/):
    like FULLSCREEN -ResX=1920 -ResY=1080

    Tested on nvidia binary (337.19 on GTX470) runs well on both profiles..
    Tested on amd fglrx (catalyst) 14.4: visual issues in both modes (GL3 and GL4) altough GL4 path has more visual artifacts..

    Problems:
    1)On Mesa currently doesn't work.. (bug tracking here:https://bugs.freedesktop.org/show_bug.cgi?id=78716)
    Anyway you should need GL >=3.2 so should be ok with oibaf ppa for nouveau but not radeonsi for that use for example (https://launchpad.net/~nzatkovich/+a...eediergraphics)..

    2) If you use a new Ubuntu distro sound doesn't work with bundled openal library I fixed overwriting libopenal.so.1 from system's one search it (in /usr/..)
    3) Demo can fail with following error:

    setrlimit() failed with error 22 (Invalid argument)
    - Max per-process value allowed is 4096 (we wanted 10000).
    will update post soon with fix I applied (required changing a /etc file)..

    Yeah, I'm getting that limit issue. Any suggestions?

    Code:
    $ ./effects 
Using binned.
setrlimit() failed with error 22 (Invalid argument)
- Max per-process value allowed is 4096 (we wanted 10000).
Could not adjust number of file handles, consider changing "nofile" in /etc/security/limits.conf and relogin.
Could not set desired per-process limits, consider changing system limits.

      for fix the error I edited /etc/security/limits.conf
      changing the line with nofile to "* hard nofile 10001" ..

        Haven't seen the specific error messages I see with latest mesa.

        Why "Runtime/OpenGLDrv/Public\OpenGL4.h"? Is OpenGL 3 stuff in OpenGL4.h?

          This particular error should be fixed with current git version of engine, but RCL said me on IRC that even latest version of engine don't work on Intel drivers yet (he didn't tested it with other drivers).

          If you want join #ue4linux at irc.freenode.net. There is plenty of good guys as well as Epic employees and one of guys was nice and shared pre-compiled shootergame for me, unfortunately it's didn't worked with same errors.

            Why exactly do they want 10k open files, in a game. Epic, proper programming is calling, you might wanna take that.

              We don't open upfront anymore and instead let them fail later. This is mostly needed for editor (and uncooked games), packaged game can start Ok without that. In the above demo, just pass "-pak" to avoid having to increase limits.

                Worked a charm, thanks.

                In related news, my usually [still] excellent GTX580 sounded pretty asthmatic during some scenes. At 1920*1200 it was down to ~17fps This is the first engine that has truly stretched this card on Linux.

                  Doesn't run for me, running with -pak I get the message "Using binned." and that's it.

                    Check that the rar file has been correctly extracted. Ark didn't do it properly for me, had to use "rar -x" :P

                    For me it does not work, I get this log:
