particles behind actor?!

POM

is it possible? or do i have to constrain another actor behind it with the particles rule?!

p.s
i dont want to start a new topic, i have another qestions..
my game run at 50-60 fps , can i force it to run at max 40? and reduce ram?
probably not but it worth asking..

Constrain an invisible particle emitting actor behind the actor you need to emit particles behind itself...at present, it's the only way. :-(
