Skeleton (.sklb)

A Havok skeleton, used for all of the animated characters and objects in the game. FFXIV uses the Havok SDK to do most of the heavy lifting for animation, so there’s not much here.

Reading #

The first few bytes are the magic, which should be a int32_t that equals 0x736B6C62. Then, there is a uint32_t that describes which version the skeleton is.

This is used if version is 0x3132_3030:

struct SklbV1 {
    uint16_t unk_offset;
    uint16_t havok_offset;
    uint32_t body_id;
    uint32_t mapper_body_id1;
    uint32_t mapper_body_id2;
    uint32_t mapper_body_id3;
};

This is used if the version is 0x3133_3030 or 0x3133_3031:

struct SklbV2 {
    uint32_t unk_offset;
    uint32_t havok_offset;
    uint32_t _unknown;
    uint32_t body_id;
    uint32_t mapper_body_id1;
    uint32_t mapper_body_id2;
    uint32_t mapper_body_id3;
};

The rest of the file is the Havok binary tagfile format which you will probably need the Havok SDK or another method to read. The data starts at SklbV1::havok_offset or SklbV2::havok_offset and is contiguous until the end of the file.
