The listing does not match what was delivered. The page says this is a textured, ready-to-use 10-room dungeon with lighting, and that you must use the FBX for lighting. dungeon.fbx is 4,108 bytes: a Blender 3.4 FBX header and nothing else. No meshes, no lights, no materials. A real FBX for this scene would be tens of megabytes, like the OBJ. The OBJ is a real mesh with UVs and mtllib dungeon.mtl, but the download has no dungeon.mtl and no PNG/JPG maps. The X3D is the same grey scene: material names only (grey, brown, flame, metal_grey), every color 0.800 0.800 0.800, no image textures. What you actually get is an untextured greybox floor plan. No scratches, no chips, no lighting. I messaged the seller asking for the real FBX plus the MTL and maps and got no reply. Please upload the complete FBX and texture pack, or refund the purchase.
