I've created a new resource that will go with my Techtree. It's called herbs and is used with my hospital. The only problem is this: The hospital heals fine, but it is a building and moves, which looks kinda freaky. I've added a range to its heal skill, but it still moves right next to the unit.
In other things, I also need free G3D models for my techtree. All submissions will be credited!
