You should be able to do something like this to get the point positions on
a per-frame basis:
import pymel.core as pm
pars_shape = pm.PyNode( 'particleShape1' )
for frame in range( start, end+1 ):
pm.currentTime( frame )
positions = []
for pt in pars_shape.points:
positions.append( pt.worldPosition )
f = open( '/tmp/parPositions.%04d.txt' % frame, 'w' )
f.writelines( positions )
f.close()
You could also use the 'with' directive for better file stream handling.
Cheers, Ken
