VFX graph sample in HDRP of the water lanterns in Ghost of Tsushima. The sample is mainly meant to educate people on how to VFX graph to create believable in-game effects that can interact with the player. The graph is fully commented and organized so hopefully you should be able to just open it and read through it.
This article was a great reference point for building this system. I would recommend it to anyone looking to use similar effects as it provide a great overview of the inner workings behind most of the effects in the game.
With the exception of the 3D assets and its associated textures, you are free to use this graph without any restrictions whatsoever (including commercial). Crediting me is not necessary but greatly appreciated!
