Thanks so much Julian,

I have created two atttributes, the RampPosition V where I have added an "arrayMapper5.outValuePP and RampPositionU where I have added an "arraryMapper6.outValuePP.

This is the part that you guys provided to me and for the position of x and z I used the RampPosition V and RampPositionU.

float $pos[] = particleShape1.position;

float $pos[] = particleShape1.position;

particleShape1.position = <<particleShape1.rampPositionU, sin($pos[0] + frame/24), particleShape1.rampPositionV >>;

However this does not work. I get only one particle moving for like 10 frames then it disappears.

Sorry if I am totally off track however thank you for your help.

I couldn't post the image, I got an error saying that new users can't post images.

I'll just send you the maya file via email
