Hi,

If you make particle emit from a poly object with the help of a PSurfacePostion node (poly object) and a PSetData (with position port on it) like it is in the dew example on your site Sadie, what is the utility of the PMotionInheritance node ?
when you move the poly emitter the particle moves too even without it.

thanx a lot

Hi,
this depends on where you get your particles from that you use with PSurfacePosition.
If you take them from PStorm or PBorn they won't stay in that place after birth if the object gets moved. In this case you need PMotion Inheritance which allows for the particles to be affected by other forces as well.

If you are using PPass to get the particles they will stay in place all the time but can't be affected by Gravity etc, since they will be set back to their original position all the time.
Hope this helps
