I have been experimenting with ways to make particles interact with 3D objects, such as in one of Unity’s sample scenes where it flows through their logo, that was using a vector field. I’ve been trying to create a satisfactory vector field with not so great results using the ‘Vector File Pro’ package from the store.
In order to convert I have to first draw a curve around the object and then duplicate a load of small boxes on that curve, since each separate vector is create from the object z forwards axis, then input it into vector field pro:
And this is the result when plugged into a VFX graph:

Not exactly great eh? So I would like to give signed distance fields a try, but it seems like a more complicated process, especially for a lowly artist such as myself who doesn’t know much in the way of coding.
So I would like to ask those more in the know on this what the best options are? Is there a way other than vectorfields or SDFs to attract or otherwise effect particles in the VFX graph that I don’t know about?
