Prompt
Highly detailed 3D model of Spinosaurus aegyptiacus, anatomically-informed by recent reconstructions. Emphasize massive, heavy-bodied semi-aquatic morphology: broad, deep torso and wide pelvis, thick robust ribs and limb bones, heavily muscled shoulders and hindquarters. Head: long crocodilian snout with conical non-serrated teeth, retracted external nares. Sail: tall neural spines forming a pronounced, slightly curved sail with alternating vertical dark stripes (use provided reference silhouette for stripe rhythm). Tail: laterally compressed, powerful paddle-like tail with a distinct ventral/caudal fin — a low, continuous skin/membrane extension along the underside and distal sides of the tail (not just dorsal) that increases tail depth and surface area for swimming. Show visible muscle bulks and chevron/hemal spine integration supporting the ventral fin. Tail cross-section noticeably thickened (not thin): strong base tapering gradually but still deep to tip, conveying swimming power. Proportions & posture: slightly crouched, low center of gravity, weight-bearing stance with hindlimbs semi-spread; broad, plantigrade-like footpads partially splayed, toes with robust claws. Forelimbs muscular and capable (powerful humerus and forearm), but overall silhouette dominated by deep trunk and sail. Convey scale and mass with thick skin folds, fat deposits along flank and base of tail, and heavy bone/soft-tissue silhouettes. Surface & textures: PBR-ready maps (Albedo 4k, Normal 4k, Roughness 4k, AO 4k, Displacement 4k). Skin: dense small tuberculate scales across flanks, larger keeled scales along dorsal ridge and limb creases; sail membrane thinner with subtle translucency and visible fiber direction. Add subtle wetness and water-bead gloss on belly, ventral tail fin, and lower limbs as if recently emerged from water; small mud smears and water streaks on lower flanks and tail to emphasize interaction with environment. Coloration: base olive-green (muted) with sandy/beige ventral underside; darker brown/charcoal mottling on flanks; sail patterned with alternating dark brown/black vertical stripes and pale cream bands following the reference. Ventral tail fin slightly darker than midline belly with faint striping echoing sail pattern. Specular/roughness: lower roughness (slightly glossy) on wet/muddy areas, matte on dry dorsal scales. Subsurface scattering for thin jaw edges, sail membrane edges. Topology & output: fully UV-unwrapped, quad-dominant clean topology. Provide high-poly sculpt (2M–6M) with baked normal/displacement, and a retopologized game-ready low-poly LOD (30k–80k). Include rigging: IK hindlegs, FK spine segments, tail IK/follow, jaw + eyelid bones, and basic blendshapes for mouth/nostril/eye expressions. Export formats: GLB (primary) + FBX (with rig) + OBJ backup. Use provided reference image for sail silhouette and stripe placement; prioritize accurate sail shape and thick tail profile as shown.
