Nice concept! How did you got the "roaming" effect of the sheeps?
Thanks! I used a simple navmesh from unity, I played just a little bit around the agent property (size, colliders, ecc..). The sheep's animation did the rest. For the alien ship I used instead an A* pathfinding (graph-based), if you are curious this is the tool I used: https://arongranberg.com/astar/.
