Particle movement direction and object rotation

I need to get a connection between the rotation value of the scattered object and the direction of the particle movement.
For example, the face of a character faces the direction of particle movement.
I tried to use the utility to get the motion vector. But still failed.Particles from houdini。
Thank you

Hi,

There are several ways to achieve this. In this example, I use the velocities of the particles to orient the instances.

You can also export the orient property from Houdini to control the rotation like in the falling computer project that comes with our content (downloadable in you download area)

Cheers
