CCWaves3D, CCRipple3D doesn't work after enable kCCDirectorProjection2D

cocos2d-x C++
#1

Hi,

It seems CCWaves3D/CCRipple3D doesn’t work if project is set to kCCDirectorProjection2D:

CCDirector::sharedDirector()>setProjection; // must be removed, otherwise the code won’t show any effect
CCActionInterval* waves = CCWaves::create, 5);
background>runAction(CCRepeatForever::create(waves));

Any idea? I’m using cocos2d-x 2.0.4

Thanks,
