Looking for a way to manipulate vectorfields in runtime in c++. i’d like to create / manipulate rather than working with effecors. all the discussions i found ran empty 
thanks for any hint / advice!
I’m not experienced enough with c++, and I don’t know what your use case is
However, if you’re making an FX, what you could look into instead is a plugin that allows you to import and read OpenVDB and NanoVDB files
You can also import sequences of VDBs, essentially having volume texture sequences; a good alternative to achieve something similar to a vector field that changes over time.
hey obriz, thanks for the reply 
think i found a solution by creating a rendertargettexture and plugin that one to niagara with a custom node. i need to kind of change the directions of the flowfield interactivly rather than fixed/baked. and i really like to create things directly in UE if possible also to just check the possibilities. the VDB importer looks amazing though!!!
