Help editing halo modles and importing them bak with Blender

[AKG666]

Ok I have been modding halo pc for a while. I used milkshape 3d before but now i am trying to use Blender to edit the halo .OBJ files. I use halo map tools3.5 to export the modle from the game and then import it into blender. I always get an error saying "Error:Can't Inject Indice problem, maximum amount of indice allowed for this modle: 3904, your modle has: 4238." when improting back to the game from blender. With mikshape all i did was export the modle from the game open it in milkshape, edit it then export back into halo. With Blender i dont even change any thing in the modle and it gives me that error when i put in back into halo map tools. Some one plz help. Note: There are quite a few importing and exporting options in blender for the obj modles i always leave them at what they are set at and never touch them
