Blender ModelTexture Recolor

I have a fully rigged character built in Blender whose surface is entirely metal-based armor. I need every visible material on this model re-themed, not just tweaked. Think of it as wiping the existing palette clean and replacing it with a fresh, cohesive color scheme that still respects roughness, metallic and normal map detail. You will work directly in the current .blend file, update the node setups (principled BSDF is fine), generate the new PBR texture set, and make sure the UV layout stays intact so nothing shifts when I re-export to my game engine. Deliverables • Updated .blend with revised materials • 4K PNGs (base color, metallic, roughness, normal, AO) ready for import • A brief note on any changes to shaders or image names so I can slot them into my pipeline without hunting for references I’ll consider the job complete when the armor shows the new colors consistently under HDRI and point-light tests with no seams or artifacts.
