I used the following code:
Graphics3D 640,480,16
SetBuffer BackBuffer()
Type SurfType
Field Surface
End Type
Global Mesh = CreateMesh()
Global Surf = 0
Global camera = CreateCamera()
Global VertCount = 0
Global PolyCount = 0
Global SurfaceCount =1
SurfData.SurfType = New SurfType
SurfData\Surface = CreateSurface( Mesh )
Surf = SurfData\Surface
SurfaceCount = CountSurfaces( Mesh )
Global ActPoly=0, ActVert=0
;so cam isnt facing mesh
MoveEntity Camera, 0, 0, -100
TurnEntity Camera, 0, 180, 0
While Not KeyDown(1)
If KeyDown(1)=1 Then End
If CountVertices( Surf )>50000 ;limit checks
ActPoly = ActPoly + CountTriangles( Surf )
ActVert = ActVert + CountVertices( Surf )
SurfData.SurfType = New SurfType
SurfData\Surface = CreateSurface( Mesh )
Surf = SurfData\Surface
SurfaceCount = CountSurfaces( Mesh )
EndIf
If CountTriangles( Surf )>18000 ;limit checks
ActPoly = ActPoly + CountTriangles( Surf )
ActVert = ActVert + CountVertices( Surf )
SurfData.SurfType = New SurfType
SurfData\Surface = CreateSurface( Mesh )
Surf = SurfData\Surface
SurfaceCount = CountSurfaces( Mesh )
EndIf
For b=0 To 15
V1= AddVertex( Surf, Rnd( -50, 50 ), Rnd( -50, 50 ), Rnd( -50, 50 ) )
V2= AddVertex( Surf, Rnd( -50, 50 ), Rnd( -50, 50 ), Rnd( -50, 50 ) )
V3= AddVertex( Surf, Rnd( -50, 50 ), Rnd( -50, 50 ), Rnd( -50, 50 ) )
AddTriangle( Surf, V1, V2, V3 )
VertCount = VertCount +3
PolyCount = PolyCount +1
Next
UpdateWorld

End
to test the poly limits and vertex limits on Blitz as im making a simple editor for Hunted so I can do lighting etc internally within the Hunted game.
The limits I have come up with are:
~18200 polygons per surface
~54600 vertices per surface
anything over it causes a memory access violation in debug on hitting RenderWorld. Thats why the limiters are in the code above. You can have any number of surfaces, polygons or vertices within the mesh although having to many may slow down ya projects.
