Show HN: Seed3D – Generate Physics-Ready 3D Models with Millimeter Precision

I built Seed3D, a next-generation 3D reconstruction and modeling tool that turns 2D inputs into solid, physics-ready 3D models — with millimeter precision, physically accurate PBR materials, and export formats ready for any major engine.

Unlike traditional photogrammetry or AI mesh tools, Seed3D doesn’t fake geometry with normal maps — it reconstructs real surfaces, edges, and micro-details for simulation-grade accuracy and realism.

What it does

• Generates watertight polygonal meshes with crisp, true geometry

• Outputs full PBR texture sets (albedo, roughness, metalness, normal, AO)

• Delivers 6K textures that hold up in extreme close-ups

• Ensures physics-stable topology for simulations and collisions

• Exports USD/USDZ, FBX, and GLTF — compatible with Omniverse, Unity, and Unreal Engine

Who it’s for

• Embodied AI and robotics researchers

• Game, XR, and VFX developers

• Product visualization and digital twin creators

• Simulation and graphics educators

Would love feedback from the HN community — especially on fidelity, physics performance, and engine integration.

The visuals look great. Two questions: (1) pricing is in "credits" but there's no indication what a credit covers - are all conversions one credit per model or ? (2) would be helpful to see mesh topologies and texture layouts.

Thank you for your suggestions. I will optimize it later.
