Particles

New SOP Particle FX shelf with several fireworks and magic trail effects. The firework effects are divided into multiple particle components, which are rendered separately and composited together. The magic trail effects show how to create, layer, and render multiple effects simultaneously within a single setup.

Brocade Fireworks

Sets up a brocade-type firework, creating a spider-like effect that resembles delicate lace with long, trailing tails.

Peony Fireworks

Sets up a peony-type firework: a common aerial effect that appears as a spherical burst of colored lights made up of various trail types.

Chrysanthemum Fireworks

Sets up a chrysanthemum-type firework, producing a spherical burst of colored lights in the sky. It is one of the most common aerial effects used in fireworks displays.

Fireworks

Creates a combined setup featuring multiple firework types, including brocade, peony, and chrysanthemum effects.

Magic Trail A

Sets up a particle simulation of a star shape that emits fairy dust particles and smoke generated with a sparse pyro simulation.

Magic Trail B

Sets up a particle simulation that emits fairy dust particles along a spiral-shaped path.

Magic Trail C

Sets up a particle simulation of a star shape that emits fairy dust particles along with smoke generated using a sparse pyro simulation.

MPM

  • MPM now works with HeightFields. You can use a HeightField as a collision object, instead of a ground plane in MPM simulations.

  • A new Use 64-bit Positions option is now available to improve simulation stability and reduce precision-related artifacts such as grid-like gaps between particles. This is especially useful for simulations with very stiff materials.
