我正在用框架写一个剧本来展示地球。但是，当我尝试添加纹理时，它变得全白。
这是我的脚本：
<html>
<head>
<div class="navbar">
</div>
<!-- aframe itself -->
<script src="//cdn.rawgit.com/donmccurdy/aframe-extras/v3.13.1/dist/aframe-extras.min.js"></script>
<script src="https://aframe.io/releases/0.9.0/aframe.min.js"></script>
<a-scene stats>
<a-assets>
<a-asset-item id="earth-obj" src="https://cdn.glitch.com/5995a6f7-2893-46f8-a015-8513de4817c6%2F1227%20Earth.obj?1551999264805"></a-asset-item>
<a-asset-item id="earth-mtl" src="https://cdn.glitch.com/5995a6f7-2893-46f8-a015-8513de4817c6%2F1227%20Earth.mtl?1552002240966"></a-asset-item>
</a-assets>
<!-- Image links. -->
<a-entity id="links" layout="type: line; margin: 1.5" position="0 -1 -4">

</a-entity>
<a-entity camera look-controls position="0 1.5 0">
<a-cursor>
<a-entity position="0 0 -3" id="weapon">
<a-box color="blue" width="0.25" height="0.5" depth="3"

</a-entity>
</a-cursor>
</a-entity>
<a-entity environment="shadow: true; shadowSize: 10; preset:default;" ></a-entity>
<a-plane color="brown" rotation="-90 0 0"

</a-scene>

这是.mtl文件
newmtl Mat
map_Kd Earth.png
usemtl Mat
Earth.png与.obj和.mtl文件位于同一目录中，我不知道该怎么做。
您的MTL和纹理不在同一目录中。它们托管在CDN上的各个URL上。故障可能会给你一个幻觉，他们在同一个目录。
