HaloMods "Classic" Read-only Archive

Im trying to make a mod where I split coagulation in half with some kind of shield. Ive put the dune_basegate shiel on there and resized the model so it was big enough to cut the map in half but the shield didnt even work. I could walk right through it. Ive tried it with the scarab door. Once again ...

If i wanted gernades to fall from the sky throughout the whole game is that considered active scenery or more like a script

and how would i do it.
