Hi,
I’m trying to make embers of a fire particle swirl when he/she walks past or through the fire (and maybe even the flames).
I took a look at global vector field and even Nvidia turbulence to achieve this effect, but I don’t really know what the best solution would be.
1 - Nvidia Turbulence: I have to integrate Turbulence to the Unreal project and I don’t think this will be a good idea since it’s quite heavy etc.
2 - Vector field: I was thinking of attaching a global vector field to the character that interacts with the gpu particles, but I don’t really know what direction the vectors need to point to always have a nice effect (I have the feeling that the vector field needs to be different when walking forwar, backwards, left and right).
So any tips or guidance or thoughts are welcome 
thanks,
Elias
