#arch#, Atlantean Marine Archway: high-density skeletal mesh of a vaulted arch rising from submerged marble ruins, its interlocking aquamarine and pearl-like ribs carved with flowing Atlantean glyph patterns. Mesh faces undulate in wave‑crest forms around bas‑reliefs of dolphins, seahorses and kraken spirals. Generate PBR texture maps: albedo with iridescent stone and pearl veins; normal/displacement maps for glyph grooves and coral striations; roughness maps contrasting smooth runes and weathered stone; emissive maps for bioluminescent inlays; ambient‑occlusion for deep recesses. Vertex‑color guides drifting plankton glow and coral fronds. Optimize topology: high density around glyphs, reliefs and coral, smooth subdivision elsewhere.
