Particles, meshes and hairThe plug-in is able to translate particle systems defined by the RealFlow particle importer (rf_particle_import node), meshes defined by the RealFlow mesh importer (rf_mesh_import node), RealFlow RenderKit mesher (rf_flowmesher node) or Houdini’s standard particle system (particle node) to the Maxwell scene using extensions. Houdini’s fur asset is also translated using the Maxwell hair extension.
Maxwell particle, mesh and hair objects have some special parameters which can be set in Houdini via detail or point geometry attributes. The following sections describe these parameters.
RealFlow particles
The following extra attributes can be defined with the RealFlow particle import node:
| 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 particles
The following extra attributes can be defined with a standard Houdini 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 meshes
The following extra attributes can be defined with the RealFlow mesh importer:
| 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. |
RFRK mesher
The plug-in is compatible with Maxwell MesherRFRK mesher v2.2 (or above), no extra attributes can be specified.
Fur
The following extra attributes can be defined with the fur asset:
| Name | Class | Type | Description |
|---|---|---|---|
| radius | Point | float | Radius of the hair points. |
| mb | Point | float | Motion blur factor of the hair points. |
| color | Point | vector | Color of the hair points. |
