When I downloaded the player package from https://www.youtube.com/watch?v=COckHIIO8vk the player only had one animation, and it was called scene, it is played as the idle animation, however. Opening the file in blender reveals that there are no other animations, just one called scene, so exporting as fbx would not and did not work. I also tried downloading from https://www.youtube.com/watch?v=L3FJVQbnllc and it still did not work. https://www.youtube.com/watch?v=gFf5eGCjUUg contained the walk animation though.
