Fix jumping horse Animation

Hi I have files in models Maya and Animation 3dMax . One freelancer did animation of Jumping horse but he didn't get the motion of horse jumping. Horse and rider are rigged and animated. It has idle,jump and run states. I attached obstacle for example, put it in your scene and jump over it see example file attached. I need it animation for Unity. Animation must be in 3d Max. I will need fbx and max files. Look for motion of horse: [login to view URL] I have a low budget. Thanks for understanding. Thanks Olga
