Dear all,

What I would like to do is accelerating or decelerating spheres using the relative velocity between the spheres and a fluid media moving at fixed velocity (velocity that I can compute and update in my script). This value of velocity could be a float or Vector3(vx,vy,vz).

Currently, DragEngive() compute the drag force as if the spheres are moving in a resting media, it uses the absolute velocity of the spheres. 

I was not able to find the C++ file on github to check the current code and try to implement what I need...

Regards,
Nicolas
