MOT Files

Credit to Sifo and Icylittlething for their investigation of the mot and gnta files.

MOT files contain one or more animations. They can be unpacked using QuickBMS and naruto_mot.bms. Each character has a 0000.mot, 0001.mot, and potentially others. 0001.mot contains only a single animation, the idle animation used for the character select screen. 0000.mot contains battle animations, as well as the same idle animation in 0001.mot. You can replace animations with each other using the QuickBMS reimport option.

GNTA Files

.gnta is an unofficial file name extension given to individual animations of a .mot file. It's unofficial since we don't know the actual name that Eighting used.

Gnta files are a series of keyframes. Keyframes are snapshots of movement at specific moments. The game will automatically fill animations in-between each keyframe. A keyframe consists of an x, y, z, and w for all applicable joints. The joint values are the same as those used in the jcv and seq files. These were originally created using the auto key feature of soft image, a now-defunct 3D modeling program. You would give it a series of poses and it would fill in animations between them for you. 3dsmax has the same feature today.

Eighting made the animations in soft image and converted them to gnta. Reason being, they wanted their animations to be recyclable across many characters. The gnta format works across jcv files. It can store bone movement data for bones, and can even do so for bones a character potentially doesn't have. This allows them to reuse the same animation across many characters with different bones.

The universal throw for example defines movements for bones 118, 119, and 120, which most characters don't have. So in this case the animation would ignore those movements for characters it does not match against. For a breakdown of bone ids see the Bone IDs section.

Gnta files were also designed to be able to combine, in that you can ask the game to play two at once. If the joints do not conflict, the game will do so. This is how hand animations in done in the GNT games. For example, Naruto's clone summoning animation is completely separate from the hand sign animation he does to call it.

MOT Header

The MOT header defines one or more animation IDs. The MOT header is followed by 4-byte words for each animation ID. Each 4-byte word is the optional offset to that animation. If there is no animation, the offset will be 0. The animation at the given offset is a GNTA Header (and therefore a GNTA file).

Offset Type Description
0x00 u16 Padding: Zeros.
0x02 u16 Padding: Zeros. Set at runtime to 1 when header is initialized in LoadObj_readMOTHeader.
0x04 u16 Padding: Zeros.
0x06 u16 Number of Animation IDs: Total possible number of animations. May not reflect the actual size.
0x08 u32 Header Size: Always 0x10.
0x0C u32 MOT File Size

GNTA Header

A GNTA file defines one or more bone animations. The GNTA header is followed by each respective bone animation header.

Offset Type Description
0x00 u16 Padding: Zeros.
0x02 u16 Number of Bone Animations
0x04 u32 Header Size: Always 0x10.
0x08 f32 Play Speed: Lower is bouncier. Usually is between .03 and .25.
0x0C f32 End Time: Usually is between .03 and 5.0.

Bone Animation Header

A bone animation header defines one or more key frames for a specific bone. The header is always 0x20 bytes.

Offset Type Description
0x00 u16 Flags: Usually 0x0202 or 0x0000.
0x02 u16 Track Flag: See values below.[1]
0x04 u16 Bone ID
0x06 u16 Number of Key Frames
0x08 f32 Total Time: frames / 60 where 60 is the FPS.
0x0C u32 Padding: Zeros.
0x10 u32 Time Values Offset: For each key frame.
0x14 u32 Coordinates Offset: For each key frame.
0x18 u32 Padding: Zeros.

Each time value is a 32-bit float, representing the current frame count divided by 60. This is because the game runs at 60 frames per second, therefore the fractional value is in seconds.

[1] Track flag values

  • TRANSLATE = 0x01
  • SCALE = 0x02
  • ROTATE = 0x08
  • ENABLED = 0x20
  • DISABLED = 0x40
