red fox 3d model

photorealistic 3D model of a red fox in a seated, alert pose. The fox has detailed, fluffy fur with variations in red and orange tones, bright intelligent eyes, and its bushy tail is neatly wrapped around its front paws. The model should be optimized for a high-end game engine, featuring 4K PBR texture maps (albedo, normal, roughness, metallic). The scene is set in a natural forest environment for a context render.
