Why tyFlow?

tyFlow is an unofficial replacement for 3ds Max’s Particle Flow.

It is not merely an upgrade to Particle Flow — rather, it was created from scratch with a design philosophy focused on squeezing as much speed and power out of modern multi-core systems as possible. Its layout, UI and workflow are very similar to Particle Flow’s, so that anyone with past experience using Particle Flow will have no trouble making the switch.

Here are some key differences that separate tyFlow from Particle Flow:

  • tyFlow’s core features are all multithreaded

  • tyFlow has automatic realtime timeline caching

  • tyFlow’s particle collision engine is fast and robust

  • tyFlow uses the latest PhysX SDK for rigidbody simulations

  • tyFlow has a fast and OpenCL-accelerated constraint solver for simulating grains/cloth/rope/etc

  • tyFlow has built-in tools to convert particle trajectories, neighbors and constraints into dynamic splines

  • tyFlow objects are self-contained and no hidden objects are created or managed in the scene

  • tyFlow has many built-in fracturing tools for dynamic mesh destruction

  • tyFlow supports simulation cascading for fast particle initialization and hierarchical caching

  • tyFlow supports simulation retiming

  • tyFlow has built-in crowd simulation tools

  • tyFlow has dynamic mesh breaking and fracturing operators

  • tyFlow has fast, multithreaded C# scripting support for complete particle control

  • tyFlow has built-in PRT/object/cache export

  • tyFlow is integrated with PhoenixFD and supports grid-particle influence/advection

  • tyFlow is integrated with Nitrous and supports viewport instancing

  • tyFlow is integrated with VRay and supports render instancing

  • tyFlow is integrated with Deadline for batching exports onto a renderfarm

  • tyFlow has many other unique features not found in Particle Flow

If you’re frustrated with Particle Flow’s lack of development updates, persistent bugs, unoptimized code and missing features, then tyFlow is perfect for you.
