FAQ

Can I have terrain objects that are not harvestable and items that are? 

Yes, this is fairly simple to achieve. The system expects that there will be no collider on the object, and that you will use the collider that it provides. In the event that you do not want this object to be harvestable, simply create a collider on the object when using it in the terrain spawner. You will need to tick the box Enable Tree Colliders for the objects to have a collider enabled.
