Add Unweighted Bones directly in Unreal #2
Conversation

Feature is still in experimental state so please if you use it backup your project before trying to introcude the bones. It might break your existing animations, skleleton assets or meshes. 😉 Special thanks to corinadow, Vlad the Iron Clad, Orphic and J0hnC0nn0r for testing and giving feedback. |

This version does not try to release the ressources on the render thread to avoid issues with shader struct parameter validation. Special thanks to corinadow, Vlad the Iron Clad, Orphic and J0hnC0nn0r for testing and giving feedback. |

Thank you already for your contribution, we will try to get back to you asap when we find the time and of course give you feedback. Looking forward to a great review session with valuable discussions. |

Oooh nice, I was also looking for a way to delete bones. I ended up doing the whole painful export as fbx, import into engine, redo all settings as precisely as possible, process. I basically just wanted to take the UE5 mannequin and modify its IK bone setup to how my game needs. |

This will really improve the workflow. Thank you. |

Secured adding virtual bones through source and target bone name checks. Sadly the public UE API does not care about this use case. Furthermore, it seems to be that unparented virtual bones create issues while adding unweighted bones through the TTToolbox preview v0.4. |

@lakkyhb See https://github.com/tuatec/TTToolbox#how-to-contribute-to-tttoolbox. Furthermore, I already created a issue for your problem here, #10. |

- introduce root bone feature - introduce data tables for mixamo characters - improved error reporting of ik rig constraint bones solver - introduce force recompressing of all linked anim sequences (constraints the virtual bones again) - added more documentation

feature is now developed and will be merged to master, which enables me to create v0.4. |
With the current state of Metahumans it is impossible to use them with ALS, as they don't provide any ik bones so far.
Sure you can add them via Blender or any other 3d software, but then you might have to deal with importing and exporting all meshes (LODs). Wouldn't it be no better to add them directly in Unreal❓
So far there seem to be only a few plugins that allows an Unreal user to introduce a root bone or unweighted bones. But these might be to expensive for you. 😄

After this pull request is merged you can add those bones via a right click and a data table. Additionally, the data table was extended to get a Mixamo character working without renaming the bones. For details see https://youtube.com/playlist?list=PLslFX7TZAr8_rp0_Oj5v6-8HlEvKU_JKw.
First tests seem to be fine here.
Furthermore, it can happen that your virtual bones might get messed up during retargeting... to work around this issue we can trigger the recompression of animations when we restart the editor. Wouldn't be it more valuable if we as a user could decide when the recompression task should be trigger❓
To workaround this issue this node was implemented. It can trigger the process and your virtual bones will be automatically constraint to the target bones. 😉
