Advanced Multithreaded Mesh

###########################################################
# Advanced Multithreaded Mesh Build for RF5
# Make sure you cache the particles, add mesh node and save
# the scene before you start the script.
# Author: bazuka
# Version: v1.5
# Date: 2010-07-25
#how to use
#1. Run Rf5 and load the scene where you already have cached/calculated particles
#2. Add Mesh node, and tweak it as you like
#3. Save scene
#4. Load the script from Batch Script window
#5. Run the script

#Note:
#Before you run the script make sure you have nextlimit license manager running.

#Warning:
#Due the rf 5.0.1.0154 bug for command line meshing this script wont work,
#so only solution for now is to roll back to rf 5.0 or wait for new update...
