The owner didn't write this. This repo never submitted itself. The Cap'm found it on a truffle trawl and wrote its paperwork from what GitHub already shows. Picked by hand by the Cap'm on 2026-10-05: Tools to MotionBuilder that fills workflow gaps. Adds flexibility to transformations, more shortcuts and other; its own README says "All of those was invented by me, but vibe coded using Codex". 1 stars; MIT license. The owner did not submit this. Votes count; awards don't until the owner claims it.

I'm not calling your project slop! Geeze, it's a joke... Do you own this repo?

Log in with GitHub as Zachariasz. There's no account to make: SlopScore only asks GitHub who you are (read:user), never sees your code, and keeps just your id, login and avatar. Then you can:

  • Keep it, on your terms. Commit your own slopscore.md (spec) and press Refresh. Your paperwork replaces the Cap'm's, and you can submit it for Slop of the Day.
  • Take it down. One click on Remove. It stays gone; the trawl never brings it back.

The Cap'm's log

The Cap'm wrote this paperwork, not the owner. This repo never submitted itself to SlopScore. The Cap'm picked it by hand: Tools to MotionBuilder that fills workflow gaps. Adds flexibility to transformations, more shortcuts and other; its own README says "All of those was invented by me, but vibe coded using Codex". It carries the MIT license. The disclosures above are his best guess from what GitHub shows.

Is this yours? Commit a real slopscore.md and press Refresh to replace this, or remove the listing in one click. There's no account to make: you log in with GitHub.

MotionBlender

Tools to MotionBuilder that fills workflow gaps. Adds flexibility to transformations, more shortcuts and other stuff known from Blender 3D. Inspired by Blender 3D tools and shortcuts.

  • No more gizmo-based workflow. You can move objects freerly with just shortcuts.

  • Moving keys at fcurves also supported. You can rotate them to orbit tangents or scale to make them weight based. Also You can snap handlers to aim neighbour keys with one click.

  • Updated picker for multi select tools, i.e. you can select multiple effectors and change them to IK with single context menu.

    and many more.. .
    . .

Press "G" to move object around. You don't need to see gizmo for translating anymore. When moving, press "X", "Y", or "Z" to lock movment to single axis in worldspace. Press axis letter twice to change to local movement (i.e. "G" to start moving, then "Y", "Y" to move object at local Y axis).

transformations_flexibility

New control rig UI, with head, spine segments, and fingers support. Window is scalable so it fits your desire size. Also you can hide top bar, for larger UI. Also you can move buttons to vertical position for more optimized larger UI.

picker_flexibility

You can edit multiple bones (selected) in same time. Select efectors and press RMB on any of those, then context slider menu appears. Just more sliders and observe that affects all effectors. LMB on empty space to deselect, RMB on empty space to select all bones. You can also pin translation/rotation via this menu by pressing pin icons.

picker_ik_fk

Move, rotate, scale tangents on fcurves using (G - for move, R - for rotate, S - for scale). You can lock movement by pressing axis letter so if you will press G, and then Y, it will only move at Y axis. Also you can scale with locked Y axis so it will flatten all selected to median point. Hold shift or ctrl when scaling tangents to affect only one side (one tangent).

fcurves_transforms-ezgif com-video-to-gif-converter

Press "V" on fcurves window (cursor must be at fcurves window) to open context menu with tangents presets. You can break/unbreak selected tangent, change selected to weighted/unweighted tangents, align selected tangent to aim left key, align selected tangent to aim right key, break tangents and aim both sides.

fcurves_vector_menu-ezgif com-video-to-gif-converter

Use "R" to rotate selected object in viewport camera orientation. Press "R" once again when rotating to change rotation type to trackball.

trackball_rot-ezgif com-video-to-gif-converter

Use "X", "Y", "Z" to lock rotation to worldspace single axis rotation. Press same axis letter twice to change to local rotation (i.e. "R" to start rotating, then "X", "X" to enter local X axis rotation).

loc_rot_transforms-ezgif com-video-to-gif-converter

You can reset your object to 0,0,0 using shortcuts. Press alt+G to reset location, alt+R to reset rotation, alt+S to reset scale.

reset_loc_rot-ezgif com-video-to-gif-converter

Press shift+A to add new objects (all available from asset browser/templates).

add_menu-ezgif com-video-to-gif-converter

Remove all keys from IK (press RMB on effector and then RMB on "K" button)

remove-all-keys-ezgif com-video-to-gif-converter

Press "M" to mute/unmute active animation layer.

mute-unmute-ezgif com-video-to-gif-converter

RMB in story tab and select "Insert current Take to Story" to add current take (on a currently selected character) into story track.

story-resetbuttons-ezgif com-video-to-gif-converter

Select clip and then press Reset / Align Z+ to reset clip to 0,0,0 position aligned with Z+ axis.

reset-ezgif com-video-to-gif-converter

Press 0f to move selected clip to frame 0.

Disclaimer:

I'm not programmer. All of those was invented by me, but vibe coded using Codex. It may contain bugs and/or absorb more performance then it should... but at the end of a day it make you work faster. Inspired by Blender 3D solutions. Some of solutions totally copied. Some of them upgraded.

INSTALLATION:

Choose scripts you'd like to use or download whole config folder and merge with:

C:\Users\%USERPROFILE%\Documents\MB\[VERSION]\config\

AND

copy or create symbolic link of "custom" folder from Scripts and place here:

C:\Program Files\Autodesk\MotionBuilder [VERSION]\bin\config\Scripts\

.

Second folder is needed for easier setup in ActionScript. If you rather not use it, you will have to rewrite paths in ../config/Scripts/ActionScript.txt

It was tested on motionbuilder 2025 and 2026.
