Hi, I'm wondering if there's any good tutorials or example on creating a Flock system for birds flying around?

I would like to have create something similar to a bunch of particle points following a single point leader going in a direction.

Hi, I cannot point you to any tutorial , but you should look at using the crowd system.its already been used for that sort of thing

Any possible hip file example? As currently now I'm trying out the Particle Flock instead, which is pretty decent.

Look at the POP Steer DOP nodes
E.g. POP Steer Seek will make them follow targets from SOP context.
