There’s a simple setup in Houdini that could be made (still need to test it) posted here by Partikel
- that’s for Unreal engine though, with free vector field files to play with (can’t convert them to Unity .vf format)
I’m still uncertain if there’s an exporter from Houdini to Unity though.
like it must be a special ROP node to export to .vf files
// also there are tools like megaflow or vectoraygen/jangaFX but you have to pay for them
I’d rather use houdini indie for that.
