Exporting models and animations from the game for use in Unreal Engine.

To stop the movement animation, simply delete the animation keys along the "Y" axis for the root bone that connects to the model's coccyx – Attachment 75777

Yes, it’s indeed a great method, and no intermediate conversions are needed; thank you!

However, I noticed that in some models, several bones move forward along the Y-axis (I suspect this happens when the model consists of multiple meshes). In general, you can quickly identify these bones by exporting the animation to SMD and then running a script that tracks which bone numbers move forward along the Y-axis during the move animation. After that, you can remove the animation keys for these bones in 3ds Max.

Although, I just tried using this method to fix the move animation for the swordsman, and in his case, this method didn't work. Four bones are moving: 1 - Sword_joint, 2 - Shield_joint, 3 - SpeedLineSword, and 9 - Hip. They ultimately move the same distance, but their frame-by-frame shifts don't match. If you try to simply eliminate the forward movement for these bones, the sword and shield will not move along the Y-axis, and as a result, in some frames, the sword and shield start falling out of the swordsman's hands.
