Create a classic Roblox-ready shallow 3D map evidence prop in Default style for Returnbound: scratched anonymous marks on an old doorframe or wall, target size 3.00 x 2.00 x 0.08 studs, 1,000 to 1,500 polygons preferred and never above 10,000, broad simple scratch shapes, chunky readable grooves, worn wood or paint through simple color blocks, a few blue-gold memory-lit grooves, subtle and inspectable, no gore, no readable words, no real names, no logo, no URL, not photorealistic.
