Krakatoa™ for CINEMA 4D is a volumetric particle rendering plugin. Krakatoa C4D is fully integrated in the CINEMA 4D User Interface. It implements various dedicated scene objects like a PRT Loader for loading particles from external file sequences, PRT Volume and PRT Surface for converting geometry volumes and surfaces to point clouds. Both native CINEMA 4D Emitter and TP particles, as well as 3rd party X-Particles and Turbulence FD systems are supported natively via dedicated intermediate objects.
The Krakatoa renderer is CPU-based, highly optimized and heavily multi-threaded.
Krakatoa’s memory footprint adapts dynamically to the requested features, with a minimum memory usage of 26 bytes per particle.
Krakatoa supports volumetric and additive particle shading and allows the mixing of the two modes.
Krakatoa features both Particle (aka Point) rendering and Voxel rendering modes.
Self-shadowing and shadow casting from matte (holdout) geometry objects are supported.
Krakatoa features integrated Motion Blur and Depth Of Field camera effects.
Render-time particle Repopulation allows the creation of more particles than the original source provided.
The interactive lighting can be baked to PRT files as a dedicated Lighting channel and allows for fast re-rendering of pre-lit particle assets, as well as for basic relighting techniques.
Krakatoa C4D supports both native CINEMA 4D Emitter Particles and Thinking Particles; external particle sources loaded from disk via the PRT Loader object; procedurally generated particles from geometry volumes and surfaces via the PRT Volume and PRT Surface objects; and fractal-based distributions via the PRT Fractal object.
Currently supported external particle file formats are Thinkbox’ PRT file sequences, RealFlow BIN file sequences, and ASCII Comma-Separated Values CSV sequences.
Krakatoa C4D includes the ability to save particle data to PRT files. It ships with an integrated option for PRT Saving/Partitioning for generating multiple wedges of the same particle system.
PRT Loader objects can be used to load one or more external file sequences. The PRT Loader allows for particle retiming using offset and animation curve controls.
PRT Volume objects can be used to fill the volume of a polygon mesh with particles and provides the option to distribute particles within a range from the geometry surface.
PRT Surface objects can be used to quickly distribute random particles on the surface of a polygon mesh.
PRT Fractal objects can be used to create procedural fractal particle distributions based on a random seed, iterations control and several animatable parameters.
Particle Channel Operator Tags
Using dedicated CINEMA 4D tags, Krakatoa exposes several channel data operations that can be used on any valid particle source usable by the renderer.
These operations include the setting of a Float or Vector Channel to a new value, the Scaling of an existing Channel by a Scalar factor, the Copying of one Channel into another, the assigning of a custom channel as UV coordinates to be used by a Texture tag for advanced mapping effects, and the Repopulation of a particle system using Krakatoa’s render-time particle multiplication algorithm.
