Maximum Size of MultiTarget

November 18, 2011 - 11:33am #1

i built have a scene in unity with 19 image targets. 16 of them are used and combined to one big multi target. when i run the app it starts about every 10th time. the rest of the time the app starts and runs normally for a few seconds until the image freezes and the LogCat shows: 11-18 20:26:02.124: WARN/SensorService(284): dropping 3 events on the floor i guess every frame. it just ends writing this line again to the LogCat if i ForceQuit the app.
is this a known issue? i read in another thread that 14 image targets in one multi target shouldn't be a problem.
having all these targets just as normal image targets didn't give me any problems.

hi kim,
thanks for your reply. sorry it took me a while to try what you suggested. anyway i shortened the names and now the problem doesn't appear anymore. well at least i was able to start the app about 5 times in a row without a crash.
thanks for that solution. i still think this should be documented somewhere as it took a while to actually figure out that it was a problem with the qcar and not with the rest of my code.

Try something for us - rename all of your targets to have names 10 characters long or less. We've seen a rare issue with many targets and long names. Let us know if this helps.

If it doesn't help, can you possibly send your config.xml and qcar-resources.dat files to

? We'll take a look.
