The Simulation Tool

VFX simulation made easy!

Storm is a stand-alone vfx particle simulation program that allows you to quickly setup and create sand, snow, rigid or softbody-like materials for 3d graphics. It additionally offers experimental support for cloth and sparse smoke fluid dynamics!

Storm is production-proven in feature film and television projects. It offers a non-cluttered, slim UI and an intuitive and interactive workflow that lets you focus on your shots at hand.

It has been used in series and feature film productions like Game of Thrones or X-Men: Dark Phoenix and more!

Storm has industry-standard and efficient file format supports on-board that let you easily load and reference your assets and also export your simulation data! Storm’s strong viewport and slim user interface will make iterating your simulations a lightweight experience.

A node graph was recently added for experimenting with more generic tasks as well.

Storm is available for Windows and macOS.
