Root motion is not something that is easy to set up for gameplay. From what I can see in your screenshot, your root motion isn’t applied simply because you are forcing the root lock.
Foot sliding is not an easy thing to solve, it will take a lot of trial and error.
In addition, root motion is not something for beginners but you are encouraged to explore it. You may read the provided documentation. I would personally doubt that this will be the final solution. Cause you might need to do IK as well. So, since it’s just a very very very small detail that won’t affect the game (for walking forward), just focus on other stuff for the development.
