I've to say it's a really stupid movie, but the effects used there are kind of awesome.
the first effect is the liquid light flows out from a glowing ball gathers at the sword as shown in the three below pictures.
and also I'm consulting this particle effect on the sword, the sword generates slowly flowing water and it's really beautiful.
I'm not a beginner of AE so such answers as using the particular plugin or particle Illusion won't help.
Also I know how to track motion in both ae and Mocha so combining the effects to real action doesn't need to be covered.
Many thanks in advance!!!
