= a lot of NSTANCE object is used because there are usually similar objects =
therefore the number of polygons is low.
You can also use this way at cinema4d.
or you can make instance in 3dsmax to similar objects.
fbx (no materials only model)
POLYGONS : 8111 (with instance objects , in cinema4d)
VERTEX : 7792
You can reduce the number of polygons by duplicating similar objects in 3dsmax version
!!polygon numbers may vary in exported formats.!!
