NREX-SD402B — Game-Ready Locomotive (Reference-Driven Texturing) A study in believable PBR surfacing for a large vehicle, using a curated reference board and material sampling to guide color, roughness and wear. Goal: Tell a service history through materials: faded industrial paint, soot around fans, rainwash under grilles, chipped steps, polished handrails, and layered bogie dirt.
Texture callouts: 1) Roof: sun-bleached paint + soot rings around fans. 2) Sides: panel-to-panel value shifts, rivet halo dirt, vertical rain streaks by fasteners. 3)Trucks & coupler: oxide/brake dust/oil stacking; rubber hoses with softer spec. 4)Steps/rails: anti-slip roughness breakup and contact-polish. Deliverables: 4K PBR set (BaseColor, Normal, ORM) + presentation renders. Wireframe, UV layout and bake previews included in the gallery.
