MIKUMIKUDANCE VMD SOFTWARE

Since keyframes are not necessarily stored for each actual frame, the animation software must interpolate between two adjacent keyframes with different frame indices. Following the keyframe count, for each keyframe there is this structure:Ī null-terminated string representing the name of the bone to which the transformation will be applied. The final world position would be (11, 27, 33). So, for example, the bind pose of a bone is (1, 2, 3) and the VMD gives (10, 25, 30). The position data of the bones in the PMD model are relative to the world's origin, and the position data here is relative to that. Note that the position coordinates are relative to the 'bind pose', or the model's default pose. Now we get to the bone keyframe list, which starts with a 4-byte unsigned int that tells how many keyframes are listed in the file. This means that it is possible to load the VMD, but only the bones described in the VMD whose names match bones in the currently-loaded model will be able to be registered. You can regist the motion only same bone name.

If the name of the currently-loaded model does not match the name of the compatible model, the message 'This motion file is the data for.

This string is 10 bytes in the old version of VMD, and 20 bytes in the new version. It is 'Vocaloid Motion Data 0002' if the VMD was created with later versions (Multi-Model Edition) of MikuMikuDance.įollowing the magic bytes, there is a fixed-length string which tells the name of the model that this VMD is compatible with. The signature is 'Vocaloid Motion Data file' if the VMD was created with MikuMikuDance 1.30 (prior to the 'Multi-Model' version). The file begins with a 30-character 'magic byte' sequence which can also be used to determine the version of the software used to create the file. I will be updating this periodically when I am able to explain how the different sections of this file work better. Note: Once again originally written by alcexhim.

The Vocaloid Motion Data (VMD) file format is the file format used to store animations for models used in the MikuMikuDance (Polygon Movie Maker) animation program.Īny fixed-length strings whose values are described as shorter than the actual length, assume to be padded with null byte (0).
