Make sure the shader is specified in gunspec.txt to be
weapon_basic.fx and NOT
weapon_bone.fx.
This will allow non-skinned geometry to render.
Most of TF341/MP53 weapons should load in OK but since not all the shader maps are included, they will have a wierd gloss look to them unless you have global specular slider turned way down (similar issue with the fantasy weapons).
You will have to do some slight gunspec tweaks for best results. Accuracy settings are a bit different in GG as well as FOV. You will need to increase the
simplezoommod=x value slightly as well. Set to
=2 or higher should be OK. It may also be necessary to slightly adjust horiz/vert model placement as well.
