[3ds max] run/walk animation need help

Hi, I'm looking for a person or description in English, German, etc. who would explain it with a picture / video explaining how mob run / walk animation can be done rightly. I had more persuasions. but for a couple of days, these cramps are moving to 3ds Max correctly, but after exporting it , it was stayed in one place, they go round or cross throw the map.

Thanks in advance for your help.
