He said Statics, not maps.
Anyway, I found this with a quick Google search:
BF2 Mod Polycount Guidelines
Please note that these figures are still preliminary and it would be advisable for teams to initially target their models to be 75-80% of the stated recommendations. Also of note is the fact that these figures are intended to get the most out of the Battlefield 2 engine, which is designed to support 100+ players in expansive environments with a mix of urban and open settings.
Objects
Buildings Rec. Max. Polygon count
House small (i.e sheds) 800
House Medium (i.e village houses) 4000
House Huge (i.e City houses) 6000
Number of building LOD steps and reduction in poly count.
LOD0 100%
LOD1 50%
LOD2 10%
Misc. Objects
Smaller object doesn’t have any strict rules since it is impossible to categorize them in to groups with a strict poly count.
Examples from FH2:
^That counts as a "Shed" I think, but (according to
the FH2 Wiki Toddel) it has
~1200 542 polys.
^That might be a ""Medium House," but it has
~6000 2373;1641;1912 polys from left to right.
^And that is definitely a "Large house," but it has
a whopping 14322 5958 polygons.
