This is my hudgun model, ( I am not a 3d modeler but do not ask for, I try to learn it ) at currently without hands, and world model. I maked it for my personal using, but now you can use :) if you wish...
Modelling in : Wings 3D
Animated : Misfit model 3D (very simple shooting animation changes later)
Sound effect: Free from the internet without any readme or license file/Audacity 1.3
Texture : Adobe Photoshop CS3
Renderer: PovRay
License: nothing! Use as you wish all content.

Usage:
- Make a backup for your sounds.cfg file here: Sauerbraten/data/sounds.cfg (rename it)
- Unzip the rifle.zip package to your Sauerbraten head directories. This make a "blue" folder here. Grab this and copy in to your favorite playermodel folder: Sauerbraten/packages/models/captaincannon/hudguns/rifle/
Before you copy this, rename the original "blue" folder here!
No need "red" hudgun model because you are always "blue" and the enemy always red.

Effects: beautiful chrome effect on enviroment mapped maps (injustice) and of worse quality on the totally closed maps (fanatic quake)

Known issues: In deathmatch mode if you are in "neutral" team you can not see the rifle model.
