<p dir="auto">I was getting a problem where the only lighting affecting the json model, with its default phong shading, was ambient.</p>
<p dir="auto">I believe the issue was the bump scale array as changing this to a value to not an array ie 1.0 fixed the issue for me...<br>
<code class="notranslate">"mapBumpScale":[10.0,10.0]</code></p>
<p dir="auto">Is this a new feature for bump map materials that we are be able to adjust x and y offset?...and for what version is this compatible with?</p>
<p dir="auto">Json Exporter vers 1.5.0<br>
r77 (npm version)<br>
Blender 2.77<br>
OSX Mac El Capitan 10.11.6</p>
<p dir="auto">When exporting a model from Blender to the threejs json format the materials bumpScale properties are arrays, while threejs expects regular values.</p>
<p dir="auto">Actual export:<br>
<code class="notranslate">"bumpScale":[0.1,0.1]</code>]</p>
<p dir="auto">Expected by threejs:<br>
<code class="notranslate">"bumpScale": 0.1</code></p>
<h5 dir="auto">Three.js version</h5>
