well... ive figured it out... i just had to change my objects bones/goals hierarchy.

now i have another question. how to make the emmiter stop emmiting particles at i.e. 30 frame?

nope... i did not :(

when i choose fx linker to make copies of the animated fish to particle emmiter... it does it... BUT... the goal objects for all other fishes are taken from the first fish... guess what is happening? every tail is pointing to the same goal... ;\...

ive used ik rig on my fish...

please people...

;\ HELP!!!

well... ive found the way to do it (thanks to Pazur for the tip)... ive done MD Scan over animated fish. than i threw out the bones and all the ik stuff. added deformation to the fish geometry with MD again... and... voila! the particles play nice now :)

LW is AWESOME!

That's probably the problem then. Use motion baker on your fish'es bones OR I would use MDscan (displacement plugin) to save out their displacements. You can then use MDplug with that swim.mdd on each fish and get rid of your bone/ik motions stuff completely. Then use FX linker on this displaced fish, and offset the start time in MDplug for each fish. Make sure Key move is on in MD plug too!)

Sounds a bit complex at the moment, but that should be sorted by 8 from the looks of things :)

For animating fish I chose not to use IK because LW bones are additive. You probably know this but it is a great trick. Just select several bones (this is without any IK or gols or anything) from the tip of the tail as far up the spine as you like. Select the rotate tool and play away.
Check it out. open a new scene. add a null. Add a bone to the null and add several child bones(=). Select all the bones press r and rotate away. Makes a great fish tail dolohin fluke elephant trunk tentacle etc.
