Large Symbol Sets
Applying 3D symbols to a large set of points can result in slow processing paticularly if the 3D symbol has a large number of polygons in it.
The maximum number of rendered symbol polygons (number of points * number of polygons per symbol) is set in the Softree.ini file:
[Terrain]
Sym3D_MaxPoly=200000000 // default is : 200,000,000
