Krakatoa Turbulence FD Source

Introduction

  • The Krakatoa renderer requires scene objects that can generate particles to provide a Krakatoa-compatible particle stream with all data to be rendered.
  • The Krakatoa Turbulence FD Source object implements the conversion of CINEMA 4D 3rd party Turbulence FD fluid simulator to a Krakatoa-compatible particle stream.

Creation

To create a new Krakatoa Emitter Source, select the Menu > Plugins > Krakatoa > Krakatoa Turbulence FD Source item.

User Interface

Basic Tab

  • The Basic tab implements the regular CINEMA 4D object controls and does not contain any Krakatoa-specific settings.

Coord. Tab

  • The Coord. tab implements the regular CINEMA 4D Transformation controls.

Setup Tab

  • The Setup tab contains the standard Krakatoa Particle Source controls available in all Krakatoa objects.

Turbulence FD Tab

Container object picker

  • Provides the Turbulence FD Container object to send to Krakatoa for rendering.

Shader drop-down list

  • Controls the shader to use for seeding particles.
  • Possible values are
    • Smoke
    • Fire

Voxel Spacing value

  • Defines the voxel grid spacing to use for particle distribution.

Voxel Subdivision value

  • Defines the number of subdivisions to perform in each voxel.
  • The default value of 0 produces no subdivisions, resulting in only the base grid.
  • A subdivision value of 1 performs one subdivision along each axis, resulting in 2x2x2 = 8 sub-regions, 2 subdivisions result in 3x3x3=27 sub-regions and so on.

Enable Jittering checkbox

  • Checked by default.

Random Jitter Seed value

  • Controls the random distribution pattern of the Random Particle Position Jittering.
  • Default is 42 for a very geeky reason. Ask a dolphin if you can find one.

Channels panel

  • Contains checkboxes with supported data channels to pass to the Krakatoa renderer.
  • Note that the Position channel is always included implicitly and is not listed.
  • Velocity is checked by default.
  • The rest of the channels have no influence on the Krakatoa renderer, but could be enabled to include in saved PRT files.

FREQUENTLY ASKED QUESTIONS

Q: I have the Demo version of Turbulence FD and I am getting no particles.

A: The Demo version of Turbulence FD is unfortunately not supported by Krakatoa C4D due to technical limitations. The full commercial version of Turbulence FD is required.

Q: The Krakatoa TFD Source is creating no particles from the TFD Container.

A: Make sure the Smoke channel is cached with the simulation, as it is required by the Krakatoa TFD Source to seed the particles.

Q: I am trying to advect other particles (TP, X-Particles) using Turbulence FD, but the particles are not moving.

A: In the Simulation tab > Velocity panel of the Turbulence FD, make sure “Particle Velocity Scale” is greater than 0% (100% would be best).
