[SOLVED] Particle designer plist when repeating plays in Cocos2d but not when single run like an explosion

Particle designer plist when repeating plays in Cocos2d but not when single run like an explosion

I have a Particle designer plist in Cocos2d that plays ok when I use plist that "loops" or repeats itself e.g. a rainbow but does not display when single display e.g. an explosion.

I'm using cocos2d 2.0 in a vanilla template with a plists created in Particle Designer tool.

I'm using following code with iOS 5.1... am I missing something?

-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

CCParticleSystemQuad *particle = [CCParticleSystemQuad particleWithFile:@"explosion.plist"]; //alt plist working with rainbow.plist
        particle.position = ccp(240,160);
        [self addChild:particle z:20];
        particle.autoRemoveOnFinish = YES;

Solution

It seems it has to do with the blend function, which I don't understand (Bottom right corner of config screen). For benefit of others, while I don't have a low level explanation other than to suggest changing these to GL_ONE made it visible. Can't assume that because it displays in the PD simulator that it shows on device.
