maya-particles (Authoring stage)

Typed wrappers around Maya's particle commands. Both particle families are covered:

• nParticle (kind="nparticle") — Nucleus-driven, collides with nCloth /

nRigid, cachable. The right default for new work.

• classic particles (kind="classic") — legacy particle nodes, kept for

compatibility with older rigs and MEL scripts.

Particle workflow

1. create_particle_system — pick kind, set lifespan, lifespan_mode and

particle_render_type up front.

1. create_emitter — choose emitter_type; pass targets to connect it in

one call, or omit and connect later.

1. set_emitter_properties — tune rate, speed, speed_random, spread.
2. set_particle_properties — tune the look: radius, opacity,

particle_render_type, and physics: conserve, drag, mass, bounce.

1. create_particle_instancer — replace point rendering with real geometry.

Use cycle="sequential" with several source objects for debris variation. Maya's -cycle only accepts none or sequential; random is rejected.

1. Collide with the world via maya-dynamics create_nrigid, then cache with

maya-dynamics create_ncache.

Scale note

nParticle inherits the Nucleus solver's space_scale. If particles look like they are moving through treacle, check maya-dynamics set_nucleus_properties before touching any emitter value.

Scripts

• create_particle_system - Create an nParticle or classic particle system

• create_particle_instancer - Instance source geometry onto a particle system
• list_particles - List particle systems, emitters and instancers
• set_emitter_properties - Edit rate, speed, spread and other emitter attributes
• set_particle_properties - Edit particle look and physics attributes
