In this video tutorial I am going to demonstrate creating a twister with PhoenixFD in 3ds max 2011. This continue my PhoenixFD series, 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.
