It's a chainsparks model, my god, it's 2011, who hasn't heard of chainsparks by now? It comes built in 1.40.
You will need a crc bypass.
Here is the hudbot stripped, with crc bypass.
Here is the full version of hudbot.
Here is my source.
On a side note, in order to bypass the server, you might need to connect using 1.11 instead of 1.30, as it is a 1.30 server downgraded to 1.0, and can detect things like certain models in 1.30.
Your best bet, use 1.11 with crc bypass, or 1.40, which comes with a built in crcbypass.
And your map issue is a lack of having the opencall maps, I belive there is two packs you will need to download.
Me personally, I'd just download this stock tribes, which comes with all the client side maps needed for LT gameplay, and either copy the base folder into my tribes setup, or start a new tribes config in the new tribes download.
Is anyone else having isues that need to be addressed?
