Re-attach flow particles to curve

[leuey]

So I loaded up my scene with my carefully tweaked partcles along a flow path, and lo and behold the particles are no longer attached to the path. They emit and just hang around the emitter. Don't know why, this is at least the second time it's done that. Is there anyway to re-attach my emitter and it's particles to the already set up flow curve? Or do I have to tweak some setting to re-set the rig so it works? I absolutely hate stuff like this in maya.

any help greatly appreciated - my deadline is fast approaching and I don't have time for [censored] like this.

thanks,

Greg

Are you sure it's not a particle caching problem? --Try deleting your old cache and creating a new one...

If you still have the problem... I dunno, maybe just copying the settings from the old Flow and then creating a new one with the same settings would work.

Other than that... you could poke around in the expressions created by the CurveFlow utility and see if you can figure out what went wrong, and where. The particles should be going towards a null object at the origin... with individual GoalOffsets determined by some noise functions and ramps and such... I'm not sure what could make them stop following the path like this.

Sorry I couldn't be of more help.

yeah, I tried clearing the cache. didn't seem to do anything. I ended up just re-creating it. The only difference between the original scene and the re-created one is I used the connection editor to transfer attributes from one flow curve to the symetrical one. Maybe that's what goofed it up.

thanks for the response at any rate,

best,

if you are using curve flow , Try checking your Maya Settings in settings/prefrences ....make sure they are in centimeters .... i hope your problem will be over.

this happens all the time & it's really a pain in the ass. i don't know why, but switching to centimeters & adjusting the positional tolerance helped fix it.

here's my settings:

preferences/
settings/
linear = centimeters
positional = 0.065 ( adjust until it works. you can start with the default of .01)
tangential = 0.1

start with a new scene & adjust these settings.
then import just the flow curve & test to make sure
it works. then import the other stuff in the scene.
usually importing something will change the
preferences settings & screw up the flow curve especially
if the flow curve is imported last.

hope this helps!
