Im working on a project, and i got some dandelon blossoms flying around in my scene. I want them to reflect on the ground, but havent been able to come up with a good solution. I am using Particular 2.1 Normally I just mirror a whole layer, but that doesn't work with particle, since my particles are being generated on a ajustment layer, and putting mirror on that will reflect my entire scene. Is there perhaps a plugin that would me make a reflective surface which you could use to reflect particles in 3d space?
What im using:
Adobe after effects cs4
theres any number of ways for you to duplicate the effect layer...copy the comp and delete the other layers and render out just the effect with a matte and re import that movie and freely manipulate it as a reflection.. or am I missing something here...

Here's method I use for relecting particles (especially with bounce): If your camera remains stationery, it could be easy for you to use if u want to get the reflection angle perfect. This is similar to Scott's method but would retain the correct reflection in the z depth:
• Copy your comp
• switch off all layers except your camera and particles
• move you cameras Y axis to the opposite height by adding the comp screen height (ie, in 720P, if you camera is at default dead center, it would be positioned at x:640 y:360 z:default, reposition Y to 360+720=1080). Keep the point of interest the same.
• In the original comp, add the new camera comp, unlink the scales and make Y -100, switch blend to screen or add, lower trans if needed.
• From this point I reposition by eye, When using bounce u just line up the bounce points and it looks perfect, but without bounce I would just find the balance between the height of the relefction plane and the real particles.
Good luck with which ever method you end up going with!!
I know this is about a week old, but I figured I'd hop in for any forum searchers in the future or in case you're still working on it.
The easy way is a plugin! Zaxwerks makes a nice reflection one that works for particles too.
If you don't feel like spending money on a plugin, here is a tutorial you might like to follow that shows a great method that should get you some great results.

Thanks for all the usefull tips all.
The problem i first had was that I couldnt make a pre-comp with the particular ajustment layer in it, cause particular wont display if there isnt anything else in the comp.
The way I solved is was just to make a blue solid, put the effect on that and use keylight to key away the blue, then precomp that and mirror it. That did the trick :)
