A highly realistic 3D model of a tall winter pine tree. The tree should have a natural triangular silhouette with full, tiered branches. Each branch is covered in a thick, soft layer of snow, giving the tree a heavy winter look. The trunk is straight, medium-brown, and textured with bark detail. The branches extend symmetrically around the trunk, gradually narrowing toward the top into a pointed tip. The snow should look natural, slightly uneven across branches, and create a fluffy, cold winter effect. The model should be optimized for use in a video game engine (Unreal Engine 5), with clean geometry and realistic textures (bark detail, snow shading).
