unit´s collision

[Herod]

IM working in a rpg that units follow a specific hero.... But sometimes it block the way.
If I use trigger to ignore hero´s collision it will pass throught trees, walls etc... any solution?

If you add the Ghost Ability (Visible) to the Hero it allows other units to walk through the Hero.

There's a trick with Windwalk that will keep the unit visible. This is what DotA used for it's Phase Boots item (I believe).

HELP: Turn off the collision of a unit like windwalk
