搅拌机出口THREE.js

Question

我有一个问题，在搅拌机THREE.js出口，即：材料和纹理根本不出口。

为了显示这个问题，我创建了一个具有一个材质和一个纹理的简单平面。

这是通过JSON导出生成整个文件：

{ 
"faces":[41,0,1,3,2,0,1,2,3,0,0,0,0], 
"metadata":{ 
    "faces":1, 
    "type":"Geometry", 
    "uvs":1, 
    "generator":"io_three", 
    "normals":1, 
    "version":3, 
    "vertices":4 
}, 
"uvs":[[0.0001,0.0001,0.9999,0.0001,0.9999,0.9999,0.0001,0.9999]], 
"normals":[1,0,0], 
"name":"PlaneGeometry", 
"vertices":[-0,3e-06,16,1e-06,-4e-06,-16,-1e-06,32,16,0,32,-16] 
} 

在对比，这是给OBJ/MTL波前格式出口（这证实存在确实是一种材料和质地组为模型）

...及其相应的MTL文件...

我觉得荷兰国际集团有关使用这些生成的OBJ/MTL文件，但three.js所R73（我更喜欢在新的阴影格式），似乎有一些问题与他们：

[.CommandBufferContext]RENDER WARNING: Render count or primcount is 0. 

无论如何，我想使用JSON格式因为这对我来说更自然，而这正是其他人在别处建议的。我很抱歉，如果这种缺乏物质的问题是真的，真的很愚蠢:)

这里是.blend文件，也许我做错了什么或有一个复选框取消选中某处...？ https://github.com/Scharnvirk/wingmod/raw/blender_issue/models/wall_pipes.blend

在此先感谢！

three.js导出器有很多选项，请检查每个材质/ UV选项是否打开。

用下面的选项中启用

我得到以下JSON
