In Vanilla Team Fortress 2, every rocket launcher reloads the same kind rocket, which makes no sense since each rocket acts differently and each rocket launcher is different.

NO MORE!

With this mod each rocket launcher reloads a unique rocket that's tuned to be more consistent with its own style associated with its respective rocket launcher.

The rockets also support warpaints for all rockets launchers with warpaints.

Misc Fixes:

Also, the plunger part of the Rocket Jumper was pushed further into its model to prevent clipping of the entire hand through when reloading.

Properly aligned the Physics model of the rocket launchers with the actual model.

Implementation:

The current implementation of Unique Rockets functions by taking the rocket models and combining them with the rocket launcher model, like the grenade models for the various grenade launchers for the Demoman.
Sadly unlike the Demoman's Grenade Launcher's the Soldier's Rocket Launchers do not have a separate $bodygroup coded in to disappear and re-appear the rocket models for when needing to reload and firing.
You might be asking if the rocket launcher doesn't have rocket model in its model? Where does the rocket come from?
Simple, the rocket model that you see when reloading is actually a part of the soldier Arms model.
BUT, if you delete the rocket model in the Arms model, the rocket model in the rocket launcher model won't appear either.
So I had to edit the arms model to shrink the the rocket part of the Arms model to be super teeny tiny, so that there are no clipping issues.
Now I have the rockets can be seen in the rocket launcher in third-person, but this can easily be changed by just moving the rocket further into the rocket launcher.
This mod apart from the arms and the Rocket Jumper and Physics model alignement do not change the various Rocket Launcher models in any way.
