stomach 3d model

Create a game-ready 3D model of a human stomach for use in Unity. The stomach must be fully closed from the outside, with a smooth, clean external surface and an anatomically accurate stomach shape, similar to a standard medical stomach model. There must be no cutaways, no openings, and no exposed interior geometry. Inside the stomach, model a detailed inner lining with realistic gastric folds (rugae), matching the natural wrinkled texture of a real stomach interior. The interior details must be contained within the stomach wall, not visible from the outside. The stomach wall should have realistic thickness, enclosing the internal folds while keeping the outer surface smooth. Topology: clean, optimized, Unity-ready Polycount: medium (optimized for real-time rendering) UVs: clean, non-overlapping UV map Materials: PBR (Albedo, Normal, Roughness, Metallic) Shading: realistic organic tissue Scale: real-world scale (centimeters) Orientation: Z-forward, Y-up (Unity standard) Export: FBX
