	make object sphere sphere, 1 : position object sphere, rnd(100), rnd(20), rnd(100)
	
next sphere


do
	control camera using arrowkeys 0, 1, 1

Shouldn't make a difference if they're created in your code or imported. I don't know if there's an official limit, but in most cases your PC will probably max out before you reach it.

+ Code Snippet

make object cube 1, 1
if object exist(1)=0 then save object "cube.dbo", 1
delete object 1
for cube=1 to 1000
	load object "cube.dbo", cube : position object cube, rnd(100), rnd(20), rnd(100)
next cube
do
	control camera using arrowkeys 0, 1, 1
LOOP

easy way to find out

+ Code Snippet

o = 1
do
load object "yours. x", o
text 0,0, "loaded " + str$(o)
inc o
sync
loop

see what number it crashes or gives an error on

In the source code all object loading and creation functions call the function ConfirmNewObject in CommonC.cpp. MAXIMUMVALUE is defined as 22000000 in CRuntimeErrors.h.

+ Code Snippet

DARKSDK_DLL bool ConfirmNewObject( int iID )
{
	if ( iID < 1 || iID > MAXIMUMVALUE )
	{ 
		RunTimeError ( RUNTIMEERROR_B3DMODELNUMBERILLEGAL );
		return false;
	}

	if ( iID < g_iObjectListCount )
	{ 
		if ( g_ObjectList [ iID ] )
		{
			if ( g_ObjectList [ iID ]->pFrame )
			{
				RunTimeError ( RUNTIMEERROR_B3DMODELALREADYEXISTS );
				return false;
			}
		}
	}

	return true;
}

Too confirm this run this snippet, then change the constant to 22000001 to see what happens.

+ Code Snippet

#constant   objID 22000000

sync on
sync rate 60

backdrop on
color backdrop 0

autocam off
position camera 0, 0, -50

make object cube objID, 20

do
   yrotate object objID, wrapvalue(object angle y(objID)+1)

   sync
loop
