Why are my NPCs falling through floor?

Not sure why my NPCs are falling through the ground in my level. I have a collider on for the ground, on the NPC, and I even tried a rigidbody and freezing the constraints of my NPC. Not sure what the cause may be. My NPCs do have animations on them, but nothing that should be causing them to fall.

It looks like they are going to an animation state that does not have an animation assigned. Make sure all states in mecanim have an animation

Hello buddy, I had a similar problem last week

  • and the problem was at the Animation Pivot

Go to your Source .Fbx file that has the animation

  • Import Settings
  • Animations Tab
  • Make sure the “Rig” is Humanoid not Generic
  • Root transfom Position Y - Set It to “Feet”
