🚧 Active development 🚧

FluvioFX is currently in early active development. While we will try to maintain backwards compatibility, until 1.0 certain features may be added or removed at any time. Use in larger production projects with care.


Unity version: 2018.3+

Since Unity's Visual Effect Graph currently requires HDRP, FluvioFX requires it as well. It must be installed and configured separately (see The High Definition Render Pipeline: Getting Started Guide for Artists for more information)

Additional performance considerations

Unity's Visual Effect Graph has a key limitation preventing the implementation of a broadphase step in the physics simulation. This has a moderate performance impact on all platforms, and severe impact on certain platforms (Metal in particular). We expect to fix this as soon as we get or figure out a possible resolution. (See #1 for details)


To install this project, add the following line to dependencies in your manifest.json (in the Packages subfolder of your Unity project):

"com.thinksquirrel.fluviofx": "https://github.com/thinksquirrel/fluviofx.git"

Currently, FluvioFX requires a small patch that must be added to the Visual Effect Graph package before usage. This is needed in order to access some internal classes. Once imported, this process should happen automatically. A FLUVIOFX compilation file will then be automatically added to the current (and any future) build platforms, which will allow Unity to load the FluvioFX assembly.

If you have any compiler errors after importing or reimporting packages, try the following:

  1. Run Tools > FluvioFX > Install...
  2. If the above menu is missing or any files are still broken, try to uninstall and reinstall both FluvioFX and the Visual Effect Graph

This workaround will be removed once the VFX Graph's API has been finalized. See FluvioFXInstall.cs for the full implementation, including all file modifications.

Getting started
