I have recently figured out how to export and remaster the weapons Mackie and I made for Warband into Bannerlord-compatible TPAC files. I would like to offer these to everyone to use. There are 44 new weapons, all with diffuse, normal and specular maps designed to work well with Bannerlord's default pbr_metallic shader. These weapons cover a wide gamut of cultures and points in time; Mackie and I were both more interested in unusual designs than just another pack of swords / spears.
For newbies and non-modders: This file merely contains the TPAC files for the meshes and bitmaps. This is not a "mod". It won't add any of these cool weapons into Bannerlord without additional work.
These meshes were originally made by Mackie or me. They were unwrapped, mastered and painted by me. Neither of us requires crediting, although we'd appreciate it. There are some aspects of Warband weapons I haven't yet figured out, largely because of the state of the current documentation, like how to use vertex animations, so in a couple of cases where scabbards existed, they have not been ported forward at this time. Use as you wish.
