I installed the MeshModifications directory's files and the textures / meshes of all the other weapons that I've tried
show up in the game just fine, except for the laser pistol, which doesn't show up at all. I don't believe the laser pistol's textures are modified at all by this mod (as per original post).
I initially did not include the items_3d.xtbl file because...
- I do not like the changes that it will do. Which, according to the readme file is "Items_3d.xtbl will make the grave digger double barreled only".
- Even if it is included, the bug still happens (laser pistol still missing).
