Havok Toolset is a collection of conversion tools under HavokLib.

This toolset runs on Spike foundation.

Head to this Wiki for more information on how to effectively use it.

Latest Release

• Havok2GLTF

Converts Havok data into GLTF.

Supports animation and skeleton data.

• extension-patterns

  CLI Long: --extension-patterns
  CLI Short: -p

  Specify extension patterns for file detecting separated by comma.

• animation

  • blend-override

    CLI Long: --blend-override
    CLI Short: -b

    Default value: AUTO

    Valid values: AUTO, NORMAL, ADDITIVE_DEPRECATED, ADDITIVE

    Override blend hint.

  • sample-rate

    CLI Long: --sample-rate
    CLI Short: -r

    Default value: 60

    Specify frames per second for GLTF.

  • scale-type

    CLI Long: --scale-type
    CLI Short: -S

    Default value: NONE

    Valid values:

    • NONE: Ignore scale tracks.

    • INDEPENDENT: Input scale tracks does not affect child nodes positions. They also doesn't introduce shearing like in MATRICIAL case.

    Select desired processing mode for node scale tracks.

  • filename-anims

    CLI Long: --filename-anims
    CLI Short: -f

    Default value: false

    Use filename for unnamed animations instead of Motion[]

• skeleton

  • skeleton-path

    CLI Long: --skeleton-path
    CLI Short: -s

    Specify path to a skeleton hkx.

  • generation

    CLI Long: --generation
    CLI Short: -G

    Default value: DEFAULT

    Valid values:

    • DEFAULT: Do not modify skeleton in any way.

    • AUTO: Automatically detect nodes with children where scale animation might occur.

    • MANUAL: Manually select bones (in gen-cbones) where scale motion occurs and have child nodes.

    Set additional skeleton modifications.

  • gen-cbones

    CLI Long: --gen-cbones
    CLI Short: -B

    Comma separated bone names where should be applied scale tracks.

  • visualize

    CLI Long: --visualize
    CLI Short: -V

    Default value: true

    Create visualization mesh for skeletons. (Enforces armature object for Blender)

  • create-root-node

    CLI Long: --create-root-node
    CLI Short: -N

    Default value: false

    Force create root node named after root-node-name setting. This node is automatically generated when there is multiple root nodes inside skeleton.(Separates root motion)

  • root-node-name

    CLI Long: --root-node-name
    CLI Short: -A

    Default value: {SKELETON_NAME}

    When create-root-node is active, generate root node name from specified pattern. {SKELETON_NAME} will be substitued by actual skeleton name. For example root_{SKELETON_NAME}_bone will generate root_Refernce_bone (skeleton name is Reference)

• scene

  • units

    CLI Long: --units
    CLI Short: -u

    Default value: METER

    Valid values: MM, CM, DM, METER, KM, INCH, FEET, MILE, YARD, CUSTOM

    Input scene units.

  • custom-scale

    CLI Long: --custom-scale
    CLI Short: -C

    Default value: 1

    Set unit scale in case of CUSTOM units.

  • up-axis

    CLI Long: --up-axis
    CLI Short: -U

    Default value: Y+

    Valid values: X-, Y-, Z-, X+, Y+, Z+

    Input scene up axis.

  • forward-axis

    CLI Long: --forward-axis
    CLI Short: -F

    Default value: Z+

    Valid values: X-, Y-, Z-, X+, Y+, Z+

    Input scene forward axis.

  • right-handed

    CLI Long: --right-handed
    CLI Short: -R

    Default value: true

    Input scene uses right handed coordiante system. (Finicky with root motion rotations)
