I'm sending this message again with an attached .osgb file instead

Hi Robert,<br>
<br>
Happy Easter! :-)<br>
<br>
Sorry for the late feedback on the performance changes in the
MergeGeometryVisitor that I was involved in a while ago. But I
discovered a rather serious issue - in the attached example mesh the
last geometry (lower-left quadrant) disappears in
MergeGeometryVisitor::mergeGroup and I think it's due to it reaching
the 10000 vertices maximum. It works in old 3.4 and it's easily
reproducible in the 3.6 branch by just running osgviewer with
default optimizations, while turning off optimizations will keep the
geometry intact.<br>
<br>
I haven't dug deep enough to find the detailed cause but the last
"left-over" geometry obviously isn't added back. Hopefully you will
find the cause quickly since it wasn't too long ago you rewrote
parts of this code. If not, please let me know if I can help with
further debugging!<br>
<br>
Also, I wonder if there shouldn't be a way to control the 10000
maximum from outside Optimizer somehow?<br>
<br>
Regards,<br>
