wooden floor planks 3d model

Create a 3D model of a wooden floor platform for Blender. The floor is made of long, aged wooden planks aligned horizontally, slightly uneven with visible gaps between them. The wood has a worn, weathered look with faded gray tones, scratches, stains, and subtle dirt marks. Include high-resolution PBR textures (albedo, roughness, normal, displacement). The planks should vary slightly in width and height to enhance realism. The structure is elevated, so include basic support beams underneath if visible, but focus primarily on the floor surface. Ensure the model is optimized, with clean topology and UV mapping, suitable for real-time rendering.
