<p class="MsoNormal">Holger and Andreas, thanks 1M for multiple important steps forward.</p>

<p class="MsoNormal">Joe, I tried this morning but will not be able to keep up with all of the suggested modifications while traveling. I hope that you can incorporate as much of them as you can in your author drafts. Next week let’s again plan on model archive resynchronization – with addition of corresponding tool diagnostics when possible.</p>

<p class="MsoNormal">The problem with these models is, that several skin coordIndices are referenced up to 12 times in several HAnimJoint nodes. This is too much for a GPU accelerated humanoid. X_ITE only supports 4 references, as specified as minimum in glTF standard. This is normally enough and there are a lot of complex glTF models in the Internet, which will work.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">When HAnim was implemented as a CPU, these models also worked, but most of the models consumed so much processing power that there was no real need to talk about them working.</p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">For this reason and because it allows X3D4.0 and HAnim 2.0, I built the GPU version, with the trade-off that not all, and especially too complex models, are no longer supported.</p>

<p class="MsoNormal"><span style="font-size: 12.0pt; font-family: 'Arial',sans-serif;">Thanks, but, the today published Lief model displays but has several failures in X_ITE. Choose Look At and scroll to get it in range to view, then choose Examine to rotate. It operates by cycling through several different animations over a 100 second interval.</span></p>

<p class="MsoNormal"><span style="font-size: 12.0pt; font-family: 'Arial',sans-serif;">For the default view (X_ITE) several connections were broken in the code translation. Leif, Lily, Tufani models broken in same or similar ways, skin bindings and joint rotations. </span></p>

<p class="MsoNormal"><span style="font-size: 12.0pt; font-family: 'Arial',sans-serif;">The file labelled labelled Canonical XML worked fine in view3dscene when downloaded and renamed. </span></p>
