Houdini plugin - RealFlow integration

Maxwell Render provides a close integration with RealFlow™ fluid simulation tool.

The plug-in is able to translate particle systems and meshes to the Maxwell scene using extensions and supports the procedural workflow offered by the RealFlow RenderKit tool. The relation between the Houdini nodes and Maxwell extensions are the following:

Name	Houdini operator	Maxwell extension
RealFlow Particle Import	rf_particle_import	Maxwell Particles
Houdini's standard particle system	particle	Maxwell Particles
RealFlow Mesh Import	rf_mesh_import	RF Meshes
RealFlow RenderKit Particler	rf_flow_particler	Maxwell Particles
RealFlow RenderKit Mesher	rf_flowmesher	Maxwell Mesher
RealFlow RenderKit Cloud	rf_cloud	Maxwell Volumetric

The Maxwell extensions have some extra parameters which can be defined in Houdini with detail or point geometry attributes. The following sections describe these extra parameters.

RealFlow Particle Import

Name	Class	Type	Description
mb_factor	Detail	float	Multiplier for the particles motion blur value.
radius_factor	Detail	float	Multiplier for the original radius value of each particle.
per_particle	Detail	integer	Generates more particles from the original ones.
extra_dispersion	Detail	float	Distributes the newly generated particles with this dispersion value around the original particle.
extra_deformation	Detail	float	Specifies the generation method of the particles.

Houdini's standard particle system

Name	Class	Type	Description
lod	Detail	float	Level of detail value of the particle system in percentage (0 - 100).
mb_factor	Detail	float	Multiplier for the particles motion blur value.
radius_factor	Detail	float	Multiplier for the original radius value of each particle.
per_particle	Detail	integer	Generates more particles from the original ones.
extra_dispersion	Detail	float	Distributes the newly generated particles with this dispersion value around the original particle.
extra_deformation	Detail	float	Specifies the generation method of the particles.

RealFlow Mesh Import

Name	Class	Type	Description
mb_factor	Detail	float	Multiplier for the original motion blur value.
smooth_normals	Detail	integer (0\|1)	The mesh looks smooth regarding certain angle when enabled.
smooth_angle	Detail	float	Defines the angle below which the normals are interpolated, resulting on a smooth look.
