Hands On Surface IK System and IK Foot System

IK system based used to place the feet of the character on the ground according to the collider shape of that mesh, so in stairs, slopes, etc.. the feet are placed visually on top of the mesh, instead of being always flat in the same height, looking awkward when the component is disabled.

The one for the hands makes the character place their hands dynamically on close surfaces without animations, making both systems feel like the characters are more alive and interact with objects of the scene organically.
