Awesome!
Model of a middle ages cannon made with Blender 3D. Each part is separate as individual objects and a collection contains all the objects. Metal parts are procedural material so you can play with the mapping and size as you wish. Wood parts are photo based from my own photos.
Textures and materials include a diffuse, roughness and normal channel. I don't know if you can consider it as PBR!? Material nodes is Principled BSDF
Important!
You will have to unzip the textures folder
Even if I exported the model to FBX and OBJ, I cannot guarantee how things will look in your software.
Update: I changed the occlusion to make the model brighter, it was too dark.
