Here is easy Xpresso setup that drives X-Particles with MoGraph data. In this setup the cloner sets the amount of the XpEmitter’s particles. Emitter’s emission mode is set to “shot”. Then Xpresso iterates through the clones and sets position, rotation and color data from every single clone to X-Particle particles.
Now you can use for example XpTrail with your MoGraph setup instead using just old MoGraph Tracer object.
