naa nething cannot solve that prob. its a fault in model creation. when makin an animated model we should stop the animation like walk animations at the position where it begins from. but that really has a solution
make a copy of that model. now open it in a model editor even free version of 3d canvas may do. now i think in ur walk animation, there may be two points, once the person lifts his left leg and brings it back again, then he lifts his right leg and brings it back again, now u shld stop the animation and cut off all further frames. so it would be smooth. i just guessed this plan out, see if it works
