Created using Cebas Thinking Particles inside 3ds max, it randomly divide bacteria and uses Bullet Solver for dynamics.
You can control the timing and division percentage, but you need to dive down 😉
Note:
-Don’t change the frame sampling, I put it to per half frame.
– For more accuracy you can increase the Bullet Solver iteration so bacteria wont overlap in case you need this.
In this video tutorial I am going to demonstrate creating a twister with PhoenixFD in 3ds max 2011. This continue my PhoenixFDseries, will be focus on the spiral gravity force. If you find this tutorial too hard, please read my previous PhoenixFD tutorial.
To follow this tutorial, you need two free plugins: footools Forceviewer and Peter Waje SpiralGravity.
fooTOOLS’s Forceviewer help us to visualize the SpiralGravity.
SpiralGravity: Adjust the Inward Str, Downward Str and Angle Str, our goal is to make the force focus to inner and upper direction. This will simulate force like a twister.
Uncheck “Std Gravity” since Spiral Gravity is the only force influence our smoke.
Set Sampler type to Truc, this will render every voxel of PhoenixFD without blurring them.
Change simple color to gray.
In this video tutorial I will show you how to use free plugin “Blur’s random walk” as force, to make particle move in random/natural ways. In thinkingParticles, with help of SC operator, we can make each paper collide each other. And we will use PSeclection to manually delete the papers that penetrate to each other.
Tutorial
This technique is not limited to paper, you can apply to feather or leaf or any other stuff you like.
You need those to follow this tutorial:
(1) cebas thinkingParticles
(2) Blur’s Random Walk plugin (free). You can download from MAX Plugins.de.
Here are some important screenshots of each steps / parameters:
You can find RandomWalk in Force/Blur’s Particle & Dynamics
Viscosity: higher value make particles move more randomly, but in the end, particles will attract to specific points in space (attractor: is a set towards which a variable, moving according to the dictates of a dynamical system, evolves over time—Wikipedia ) :

To avoid this effect, we can increase the %Walk:
The Alignment Operator can randomize rotation of your geometry (paper):
Spin operator give more natural movement to papers:
In the SC operator, remember to set parameters as follow, otherwise the paper will freeze…
Use PSelection to manually pick up particles in the scene that penetrate to each other, and use Particle Die to delete them:
