I did mesh clean up, optimization, unwrap, and texturing of this asset for Red Alert: A Path Beyond ("APB"). About 90% of the modeling was done by another team member before being passed onto me for the finishing steps. APB is a free mod that recreates Command & Conquer Red Alert as a first/third person shooter.
The W3D engine that APB uses dates back to 2002 so it didn't support any kind of PBR workflow but at the time I textured this asset we were experimenting with hacking in support for more modern shading models and texture map types such as specular and normal so I included them. I don't believe that ever came to fruition so the albedo was the only map that was used.
