3D Model: Create A High-quality, Realistic 3D Model Of A Lion In .glb Format. The Lion Should Have Detailed Fur, Lifelike Textures, And Natural Proportions. Include Three Animations: Walking – The Lion Walks Forward At A Natural Pace. Roaring – The Lion Stands Still, Opens Its Mouth Wide, And Performs A Realistic Roar With Subtle Head And Body Movement. Sitting – The Lion Transitions Smoothly From Standing To Sitting In A Relaxed Posture. Ensure The Animations Are Loopable (where Applicable), The Rigging Is Clean And Optimized For Real-time Rendering, And The Model Is Suitable For Game Or AR/VR Use. The Lion Should Be In A Neutral Environment (no Background) And Well-lit To Show Realistic Shading.
