Dynamic vector field

Development Discussion C++ Gameplay Programming
#1

Hello

I’ve started looking into unreal engine receantly and I’m currently watching a bunch of tutorials just to get a grip, how things work.
I’ve run into vector fields while learning about the particle system inside the engine and I got an idea, but I can’t find anywhere if it is possible or not.

So, is it possible to set runtime the vectors inside of a vector field? If yes where should I start looking for the matrix/array that holds the vectors?

It’s not I’m afraid, you can ‘move’ the vector field itself, but the vector field data is ‘baked’ when you import it (i.e, it can’t be altered).

Modifiable vector fields would be interesting though, it’s probably something you can do with C++ - but may also be difficult since VF’s are fully processed on the GPU if I’m not mistaken (which I could well be).
