Inserted Vieport looks ok. But when I resize it to show the part I actually want to see some objects are disappearing or changing colour. Is there a fix to that? It all looks good in Raster or Hybrid. I thought maybe that had something to do with Tags or the Groups/Components disappearing is somehow faulty so I redrew them and reapplied Tags. No change.
Here are two cases with how it looks in Sketchup and Layout.
By the way - it has nothing to do with ConDoc Tools as the same thing happens when I open an empty file and simply Insert one of the Scenes from my model, re-render and resize.
