Unreal Engine project (5.7 and 5.8): all content sits in Content/MedievalCoffins/.

Maps/: Overview level (startup map) showing the five coffins in a row on a floor, lit, no light build needed.
Meshes/: SM_Coffin_01 ... SM_Coffin_05, each with LOD0, LOD1 (50 %) and LOD2 (25 %) and auto-generated simple convex collision; lightmap UV on channel 1. The iron cross (01), rope (02), iron bands and padlock (03) and chain (04) are part of their coffin mesh, on their own material slot.
Materials/: M_MedievalCoffins_Master with 9 material instances (MI_Coffin_0N_Wood, MI_Coffin_01_Iron, MI_Coffin_02_Rope, MI_Coffin_03_Iron, MI_Coffin_04_Chain, MI_Coffin_05_Stone); swap any texture through the instance parameters (BaseColor, Normal, Roughness, Metallic).
Textures/: 4096 x 4096, normals in DirectX format, Roughness and Metallic stored as linear masks.
Real-world scale (2.0 to 2.18 m long); pivot at the centre of the base, on the ground (SM_Coffin_04: on the bottom of the wooden box, the chain sinks into the floor).
