KCM help!

Krakatoa for 3ds Max
1

Hi!
there is the story:
I have a boat in the water with a good speed.
I add pflow collision to emit particle on collision like the real splash in front of boat.
I cache my particles with krakatoa
I load particles in PRT loader
I tried to render with Krakatoa only particles with Velocity???
I don’t wont to see static particles

Help

Thanks

*Add a KCM to the PRT Loader.
*Set a flow to read the Velocity channel, get its Magnitude, compare if equal to zero and send the result of the Equal operator converted to Float into the Selection channel:

*Then add a Krakatoa Delete modifier on top of the stack and you are done.

Why convert the Equal output to Float?
All logical operators in MagmaFlow use Integers to define True and False.
When the Velocity is 0, the IsEqual produces True (1) which gets converted into 1.0 and results in Selection Channel with value of 1.0 (Fully Selected).
When the Velocity is not 0, the IsEqual produces False (0) which gets converted to 0.0 and sets the Selection Channel to Not Selected.
Then the Delete modifier just grabs the particles with channel of 1.0 and deletes them.
