Blender 2.8, Exporting adds vertices

[TheHusseler]

I'm having a difficulty with a blender model I"m working on. When I export to glm, it no longer opens in modview because a surface is over 1000 verts. In blender none are however. I tried exporting and then reimporting to see if the exporting changed anything, and indeed it did. There were now 2600 vertices on one object that had previously been only 700 vertices. I have tried everything and I can't get it to reduce or export correctly

My guess is that you didn't split the mesh at UV seams, and the exporter did so automatically. Whatever the cause was, the only way now is to separate the mesh into multiple objects, each one with less than 1000 vertexes - so at least 3 parts.
