The Thunderbolt model itself is from a model pack I downloaded back in 2001 in MAX format. I still had them on my drive and decided to see if I could get it to work. After extensive modifications and trial and error, I succeeded.
The original model was created by Conor Clancy back in 2001. It was released for free use to the public back then but I none the less attempted to contact him at the hotmail address in the readme. No reply was received.
From that read me:
"This Model is not for sale and should be distributed freely
This model was created for love, not money. So please don't sue me Joe
Babylon 5 and Crusade are copyright © and trademark & trade; 1992-1999, PTN Consortium."
The table file is a full replacement for the default ship.tbl that was included in v3.73 of The Babylon Project. BACK UP YOUR ORIGINAL PLEASE.
The ONLY changes to this table file from the default are with the missile racks on the Thunderbolt, the standard EA and PSI both have three racks now like the bomber versions had, and the thrusters. The thrusters were never completed in the original ships.tbl. I adjusted them to work correctly with this new model. Beacuse the new model has three missle banks, the ships table MUST match or the game will crash.
The reason I ended up with a replacment tbl file instead of an add on tbm is that for some perplexing reason, the thruster locations were being read from both the original tbl and the updated tbm file I was testing at the same time. So that resulted in "ghost" thruster points being created that I couldn't get rid of without commenting them out in the original file. I figured if I had to do that, might as well just replace it.
So, here we are.
25 different variant combinations between nose art and color plus the Psicorps versions.
I also included an options folder with various maps and a readme to explain it along with the PDN templates I used for both the TBolt and it's cockpit maps. And another cool feature of using those options files is that the color you choose will also be used by the Thunderbolt cockpit mod. So that what you see inside matches the outside

Enjoy!
