Hello there @The_M0ss_Man ! Thank you so very much for your feedback on my project! I greatly appreciate it!
For the older rusty metal texturing, I actually downloaded a texture material from the Adobe Substance 3D Assets community page! They have a huge selection on very useful materials to use, and I found one of metal with rust that can be altered quite handily! I’ve used it in several projects, and it has served them well!
