  1. Hi Baiyanbin,
    Is it possible to set up a “spring rig” in maya (where i’ll be doing all my skinning/rigging)
    Then import the character in Mobu, characterize it.
    Then turn on the “Spring rig” I did in Maya.
    Animate my character with the rig.

    Does the Spring rig port from Maya to Mobu ?

    I would like to have that kind of workflow.
    Rig in Maya -> Animate in mobu -> render in Maya.
    Once everything is plotted in Mobu that’s not a problem for me it’s really the spring rig workflow Maya-Mobu.

    I’m really curious/interested by your solution.
    Thanks.

    1. Hi Sebastien,

      First of all, Spring Magic in MuBo is not a rigging tool, also not relia on any specific rigging set up.
      Any bone chain which has +X axis towards child bone setup and no constrain limitation, can all been cauculated by Spring Magic in MuBo, caculated result will been recorded as plotted keyframe on skeleton node, that can be export to other software with same result.

      “I would like to have that kind of workflow.
      Rig in Maya -> Animate in mobu -> render in Maya.”
      so it’s totally no problem with Spring Magic in MuBo

      and actually you can just use free Maya version Spring Magic for your pipeline, just do caculation before render in Maya

      Cheers

    1. 没有严重bug的话短期内不会更新,目前主要精力放在了其他的项目上
      如果未来有时间的话,打算会做的一个更新就是把 Max 版本新增的一些功能也整合到 Maya 和 MB 的版本里,比如平面碰撞,骨骼形状和骨骼关联等

      最后,MB 版本是付费版,没有计划要公开源代码

  2. Hi Bai!

    I have one question before I buy Spring Magic for Motion Builder.
    Does it work for Motion Builder 2017?
    If so, is it possible to bake(plot) without problem?
    Thanks!

    1. 1. It works for MoBu 2017 with no problem.
      2. The calculation result already be recorded as plotted keyframe, so you don’t really need to plot it again. But if you like, you can plot it as many time as you want, and animation will keep the same.
      Cheers!

      1. Thank you Bai!

        Maya version was excellent and you comment was very assuring.
        We purchased the script!
        By the way, do you have any volume discount if we buy more than 10?
        Thanks!
