About

Drakkar VFX is a simple VFX editor for Bevy and Hanabi.

This project is a work-in-progress and not yet production-ready. It currently focuses on 2-D particle effects. We welcome pull requests that add 3-D support, update the codebase to the latest Bevy and Hanabi releases, fix bugs, or enhance the editor's UI and features.

Thanks for helping the project grow!
