Include maps in samp.ipl

Hi,
I tried to add the Vice City map to samp to prepare a multiplayer server on SAMP (after conversion with dff/txd names of gta_sa, with the scene2res software), then I converted the .map to. Ipl, it all works. Apparently, adding .ipl files in the gta.dat does not work for samp, it does not take them into account.

So I modified the samp.ipl to add the objects. This works very well for the first 1000, but then I crashed. What to do to successfully include this beautiful map and play multiplayer on samp?

Thanks.
