I’m using ParticleMesh for Explosion, Flame tail and some effect for the Item. But, when I attach the new effect (using ParticleMesh) to the rootnode of game, there’s a line of color from the (0,0,0) to the position of effect. The picture below is error, the Red Arrow point to the unexpected line.
The same thing happens to my ParticleMesh when I use changeScale() on it's parent node… There is a stream of particles from some location (I've guessed 0,0,0) to the node location, although they are sized like the end particles of the ParticleMesh. So it is as if the particle creator has the correct start location, but the wrong end location for creating/moving particles.
