Foot IK for Unity, available in the asset store

Does not require Unity pro. Web player here: http://www.kavorka-racing.com/simplefootik-player.html Simple foot IK modifies the animation procedurally so that the feet position and angle matches the ground even if the ground is not flat. Simple foot IK also enables the character to run up and down hills and stairs. For normal biped bone riggings Simple foot IK is set-up and auto configured by just dragging and dropping the SimpleFootIK script onto your character. Simple foot IK features IK weighting for smooth enabling/disabling. Available in the asset store: https://www.assetstore.unity3d.com/#/content/15660
