This repo is a fork of Unity's VFX Graph v10.3.2, back porting features from the later versions of the VFX Graph.
The only reason for this is because the VFX Graph does not officially support the built-in pipeline, and v10.4.0+ removed support for the builtin pipeline all together.
As we have some built-in pipeline projects that make use of the VFX Graph, it is useful to keep this around locked to this version. Apparently it still works with Unity 2021.1.13f1, though obviously there's no guarantee how long this will keep working for.
We are not affiliated with Unity in any way. Old versions of Unity products are not supported nor recommended by Unity, and no support will be provided for using said products. Use at your own risk, and do not bother the folks at Unity if you decide to use this.
