While working on a release of 100+ vector fields for the Unreal community marketplace I built a few handy tools to generate vector fields from curves, surfaces etc, and to blend them with constants, noise, various forces, other vector fields and so on.
For example, here is a vector field using a spherical surface and a “pull” force to create a forcefield effect:
While this vector field uses a series of curves mixed with flow noise for a “jet exhaust” effect:
In Unreal a single cascade emitter can use these vector fields and GPU sprites to create a very broad range of looks:
So to celebrate and promote the upcoming release on the Unreal marketplace I’ve generated 10 free vector fields in .fga format for download here. Enjoy!
