I'll be doing this fire effect in unity.

This is my Second Effect - Create dust effect on his feet when running.

My character does not have toe polygons / joint in unity and i have tried in maya to mesh sparate the polygons. 

But I get an error:

character running |

walking.

Character  jumping.

I need to solve the problem but I don't how to do it, do I need to do scripting ???

When the player hit the space bar for jumping the character feet's particle dust disappear.  

So I decide to put the particle under his ankle joint.

My Setting

The Script

as for my third effect i'll be create glows effect when collected a coin the character glows.
