[Graphics] US/UM Decompressing Map Models

[TriedAndTRUE]

So I'm trying to decompress map models in US/UM. I've heard they're located at 0/8/5 in the romfs, so I tried unpacking that with PK3DS and I get an error.

Exception Details:
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: startIndex
