particle splash

I was wondering how to stop particles at a certain point.

What I want to do is have water splash on a bottle and stop while the camera is spinning around the front.

Any ideas on how to do this?

If you're talking about a bulllet time effect, your best bet is to find the frame that you want the splash to "stop", render up to that frame, then render multiple versions of that same frame from slightly different angles. This should continue to give you the motion blur one would normally see to completely sell the effect. Then continue the render from your ending camera angle as normal. It's tedious, but it is actually how the bullet time effect is done....

Oh wow. I have to set up 60 cameras to do it? Holy. It wouldn't be that bad if I could automate the renders of the multiple cameras.

How do you freeze them?

Sorry, but I'm on a Mac here. I already contacted them to see if they had a Mac version available and there is nothing available at this time. Too bad really. They would have had a sale 30 minutes ago.

been a while since I did this with Napalm and PS 2 Pro. not sure how well this trick will work with PFX (the way I did it in the others was thru built in fucntions)

with PFX, make your particle sfrom a partigon, on teh frame...frames that you want to freeze, export a copy of hte partigons, it should hold its shape. then you can just rotate your camera around them. if you morph between two or three groups over time, you should still get the motion blur in there as well.

So how do I export the particles?

if they are partigons, used "Save Transformed"

I guess I should ask...

How do I convert my particles to partigons?

I'm not sure you can convert currently created HVemitter to a Paritgonemitter. I'm hoping I'm wrong for your sakes if you already have them set up.
However if you just want to create a Partigonemitter Just choose Partigonemiiter from the 'Add:' selection of the FX_Browser (ParticleFX Browser) or from the Items tab select Add->PFX->Add Particle Emitter->Partigon Emitter under the Emitter Type:.

easier way i think.
don't use the "etc" tab in your emmiter options to set up gravity/wind.
use FX wind/gravity
set the particle's weight to 0
keep resistance normal (1 or whatever you have it set to)
keyframe the power of your FX wind/gravity to 0 when you want them to stop.
(it's the particles' weight that makes them keep going)
animate your camera normally during stopped time.

You can not convert but In a case like this what you could do is save the particle motion settings and load it to the new emitter.

Well here it is guys the final edit.... I colour corrected and composited the piece in Combustion...

The only thing I thing I would change is the blur on the background bottle... let me know what you think...

Very convincing effect - very well done. My only small and humble critique would be the orange (sunset?) background - doesn't really jive with the bottle and water droplets which are reflecting/ transmitting white light. Maybe the background could be changed to mid day background (blue sky, white clouds) to match the white light that the bottle and water droplets are showing.
