Hello guys,  
How can I modify the initialized member value of UParticle System by using ClassDefaultObject when Particle system asset created. From the google I found that every types of object uses the CDO to initialize. So I want to modified the value in CDO. But when I new an asset the value was not modifed. But when I used cascad, I can reset the value to the default value which I set in the CDO by the button beside the value box. Could anybody Know what happened?

Any Epic staff could explain if the asset object use the CDO when it is creating and initializing.
