  4. 您好，插件已购买，在mb 计算时飘带时，布料会产生扭转，不太正常，试着修改twist 值也不起作用，请问有什么解决办法吗，还有布料解算的时候能模拟重力效果吗

    回复

    1. 感谢购买，
      1. 布料扭转的问题，请确认是否以 +X 轴指向子骨骼的形式架设的骨骼链，如果不是 +X 轴或者有偏移，计算结果就可能产生奇怪的偏转
      2. 可以用一个向下的 wind 来模拟重力，把最大最小风力都设为同一个值，并指向下方，就可以得到一个稳定向下的力

    1. Okay so it was a work network issue.

      Are you still responding to comments for support?

      We just purchased and installed this script in MB2020 to test out for a client, and we are having a problem. The Spring Magic script is adding a strange offset on all bones on frame 1, if the bones are anywhere except 0,0,0. This offset takes about 30 frames to resolve back to the initial position, so we cannot use the Loop function for cycles. We are using a straight chain that was imported from Maya. The results are even stranger if I try to use a chain made in Motionbuilder out of Skeleton Node objects.

      Is there part of the installation process, or some initialization step that we missed?

  6. 对这个工具还不了解，看了介绍非常想购买。只有一个问题， 目前这个MB版本的脚本可以实现两端由自己控制。中间骨骼进行物理计算的功能吗？ 就是一段绳索，两端可以K帧和约束，中间的骨骼进行物理计算。

  12. 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

  15. 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!

    回复

    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!
