<p dir="auto">I have exported an object I made on the scene with javascript (as a shapegeometry) using the <code class="notranslate">toJSON()</code>function. Now I try to reload the object on the scene with an <code class="notranslate">objectLoader</code>, but it fails because the objectloader doesn't support geometry type <code class="notranslate">ShapeGeometry</code>.</p>
<p dir="auto">Except if I'm missing something, that means that I can't reload exported models in the scene?</p>

<p dir="auto">It may be possible to just more intelligently select the LOD level for the specular and diffuse cube maps rather than generating prefiltered ones (thus addressing this may make this other issue <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="112791185" data-permission-text="Title is private" data-url="https://github.com/mrdoob/three.js/issues/7402" data-hovercard-type="issue" data-hovercard-url="/mrdoob/three.js/issues/7402/hovercard" href="https://github.com/mrdoob/three.js/issues/7402">#7402</a> obsolete.)</p>
<p dir="auto">The key part in this paper is that it figures out first the default LOD that would have been chosen, and then modifies it using a query parameter that is derived from the cosine filter.  This requires a query of some sort for the current LOD level.</p>
<p dir="auto">Some requirements for that query -- it should not be done by packing into the current cubemap the LOD in A because A is needed for HDR textures.  Thus I guess the only alternative is to have a separate cubemap that is 8 bit luminance (to save memory) and contains LOD numbers?</p>
