Three.js使用Blender导出json文件U…

最近被这蛋疼的问题搞死：简单说就是Blender输出Three.js用文件的addon插件，其官网更新了，然后怎么也读取不了了，找了半天还以为是自己javascript程序的问题，结果发现旧的addon插件输出的js文件能用，而新的插件输出的json文件不能用。于是把旧版本插件文件给大家下载，顺带附带插件的Blender也提供下载了：

其中2个版本的区别，old版本输出的是js文件，new版本输出的json文件：

Three.js使用Blender导出json文件Uncaught <wbr>TypeError问题，原因：新插件bug

从截图可以很清晰看到新版本加了很多功能，控制面板变长了。试着在Blender建立了一个默认的立方体，看了下输出的原文件，发觉差别也忒大了：

先是json文件：

{

"uvs": [],

"vertices":[1,-1,-1,1,-1,1,-1,-1,1,-1,-1,-1,1,1,-1,0.999999,1,1,-1,1,1,-1,1,-1],

"normals":[0.577349,-0.577349,-0.577349,0.577349,-0.577349,0.577349,-0.577349,-0.577349,0.577349,-0.577349,-0.577349,-0.577349,0.577349,0.577349,-0.577349,-0.577349,0.577349,-0.577349,-0.577349,0.577349,0.577349,0.577349,0.577349,0.577349],

"name": "CubeGeometry.1",

"metadata": {

"uvs": 0,

"vertices": 8,

"normals": 8,

"generator": "io_three",

"faces": 6,

"type": "Geometry",

"version": 3

"faces":[33,0,1,2,3,0,1,2,3,33,4,7,6,5,4,5,6,7,33,0,4,5,1,0,4,7,1,33,1,5,6,2,1,7,6,2,33,2,6,7,3,2,6,5,3,33,4,0,3,7,4,0,3,5]

}

然后是js文件（old版本Three.js的addon输出）：

}

是时候该摆脱这问题了……话说编写Three.js的程序员你给我给力一点啊，我恨透这个bug了：
