嘿，如果有人可以帮我制作这个对象的动画:
上下移动| 左-右旋转 | a 查找 | z 向下看
原始文件链接:http://www.aacctrust.org/anim/anim.htm
JSON 模型文件(带有动画 tail-wag):
http://wikisend.com/download/654748/wolf.json
问题是 json 模型文件已提供有关尾部动画的必要详细信息。狼的尾部应该是摇动的。 但事实并非如此，我已经尝试了一切但没有帮助。
代码有问题还是我没有从 Blender 正确导出。
下面是代码:

最佳答案
更新:
在等待回复的过程中我进行了一次 self 探索之旅;)
并找到了一个几乎可以接受的解决方案，步骤如下:
文件 >> 导出 >> Wavefront (OBJ)
确保选中“动画”选项。
单击导出(导出时请在单独的文件夹中进行，因为根据帧数，文件可能会很大。)
复制 Blender > Python > Bin 目录中的文件夹。
将转换器从 Three.js utils OBJ for python3 复制到 Blender > Python > Bin 目录。
在管理模式下启动命令提示符并运行以下命令:
python objtothirdjs_conv_python3 -i meshdirname\meshname_000001.obj -o output.js -m "meshdirname\meshname_*.obj"
输出动画将是变形动画，并且需要对混合器进行一些更改才能播放变形动画。
关于javascript - 在 Three.js 中无法让尾部摇摆(动画)？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37026641/
