<p dir="auto">I find that the polygonOffset do not work if turn logarithmicDepthBuffer on.</p>
<p dir="auto">I have a model which contains several totally overlapped mesh surface. And I try to use <code class="notranslate">logarithmicDepthBuffer = true </code> to solve it, but no lucky. And I try to use polygonOffset, but it only works when <code class="notranslate">logarithmicDepthBuffer = false</code>.</p>
<p dir="auto">Is it a bug or just the feature of webglrender?</p>
