R06.06.02.02-T01 Texture a helmet by material ID with edge wear

原始指令

In Substance 3D Painter open fixtures/helmet.spp (baked maps, ID map: red = painted steel, blue = rubber, green = glass). Make red areas worn painted metal (paint base, metallic >= 0.9 where paint is chipped on curvature edges), blue matte rubber (roughness 0.8-0.9), green glass. Export Unreal packed textures (BaseColor, Normal, OcclusionRoughnessMetallic) at 2k to output/helmet/.
