Isgl3d and vuforia sdk

Hello. I want integrate vuforia sdk with [URL=http://isgl3d.com/]Isgl3d[/URL] framework. I changed ImageTarget example from the vuforia sdk samples. In ImageTargetAppDelegate.mm add isgl view with transparent background over the arParentController.view but I get a black screen. When I commented out this: [CODE]//[[Isgl3dDirector sharedInstance] run] [/CODE] then I normaly see my video camera image. May be something wrong with cleaning background? But I set the transparency: [CODE][Isgl3dDirector sharedInstance].backgroundColorString = @"00000000"; .. .. _viewController.view.backgroundColor = [UIColor clearColor]; _viewController.view.opaque = NO;[/CODE] This is my ImageTargetAppDelegate.mm: [CODE]#import "ImageTargetsAppDelegate.h" #import "ARParentViewController.h" #import "QCARutils.h" #import "Isgl3d.h" #import "Isgl3dViewController.h" #import "GWViewManager.h" #import "GWPlayersListViewController.h" @implementation ImageTargetsAppDelegate static BOOL firstTime = YES; // test to see if the screen has hi-res mode - (BOOL) isRetinaEnabled{ return ([[UIScreen mainScreen] respondsToSelector:@selector(displayLinkWithTarget:selector:)] && ([UIScreen mainScreen].scale == 2.0)); } // Setup a continuation of the splash screen until the camera is initialised - (void) setupSplashContinuation{ CGRect screenBounds = [[UIScreen mainScreen] bounds]; // first get the splash screen continuation in place NSString *splashImageName = @"Default.png"; if (screenBounds.size.width == 768) splashImageName = @"Default-Portrait~ipad.png"; else if ((screenBounds.size.width == 320) && [self isRetinaEnabled]) splashImageName = @"Default@2x.png"; UIImage *image = [UIImage imageNamed:splashImageName]; splashV = [[UIImageView alloc] initWithImage:image]; splashV.frame = screenBounds; [window addSubview:splashV]; // poll to see if the camera video stream has started and if so remove the splash screen.
