Quartz Builder Crash

d3lray's picture

hello,

I just purchased quartz builder to sidestep an issue with 10.7 and quartz visualizer app not working.

I'm able to bundle my quartz composer patch without an issue, I see the plugin qcOSC.plugin in the resource inspector.

The patch receives OSC messages via MAX/MSP and everything works just fine in composer.

But it crashes as soon as I start sending OSC messages. If max/msp is op[en and sending OSC before the .app is opened then it never even shows the viewer window.

checking the crash logs, it shows that its this thread is where things are crashing:

I can post the whole crash log if anyone likes, but i thought this might be enough.

Also, and possibly related, I can not seem to get the template to show up in quartz composer. The plugin is installed in ~/Library/Graphics/Quartz Composer Patches

any tips would be greatly appreciated.

Re: Quartz Builder Crash

OK,

Ive narrowed this down a bit. If I do not pass any information over OSC it is stable (of course nothing is happening either since all control comes from OSC events.

As soon as i start sending OSC messages via 127.0.0.1 over UDP, I see for a split second, some movement, and then it crashes every time in the thread i detailed above.

I am using the hexer qcOSC.plugin (0.6) has anyone used this in conjunction with quartz builder?

how about the OSC listener patch that comes with quartz composer?

thanks again matthew

I've emailed rob (hexler) , awaiting a reply. You could always try him yourself but i know he is a very busy man

Re: Quartz Builder Crash

Try keeping the qtz that loads qcosc unencrypted- try making a shell composition that loads your qtz that has qcosc, via a composition loader, then feed "that" to quartzbuilder. Totally untested, but I feel like it stands a shot. I think it's that whole "generate ports on the fly without user input" that's a part of the problem when it gets encrypted w/ quartzbuilder, but I'm only guessing.

Re: Quartz Builder Crash

well, it was a good try, but I can't seem to get a nested composition to work in Quartz Builder without the qcOSC.plugin in the resource inspector. Without it I just get a black screen.

When I add the qcOSC.plugin, it shows the correct image, but the I get the same crash. I suspect you are right in terms of the dynamically creating port thing...as i get a bunch of these in the console:

10/18/11 11:58:50.815 AM Quartz Composer: *** Invalid attempt to set port minimum; Ignored.

maybe its time to then start another thread, as the vanilla OSC object that comes with composer doesn't work when i stream a bunch of floats to it form MAX/MSP - it more or less snaps to the end value, whereas the hexer plugin allows for a stream of floats to act as it should...any clues what that issue might be?

thanks everyone! matthew
