Distortion of physical properties in 3D assets (e.g., drawer friction coefficients, object center-of-mass offsets) causes policies learned by robots in simulation to be difficult to transfer to real environments, a phenomenon known as the sim-to-real gap.

UnverifiedAI-generated 3D assets often suffer from irregular topology, uncontrollable polygon counts, and disordered UV mapping, making it difficult to plug them directly into modern game engines' LOD pipelines.72% similarUnverifiedIn Tunman's asset library mechanism, existing technology still struggles to achieve fully seamless cross-frame consistency in multi-angle action and extreme expression scenarios.71% similarUnverifiedRaw 3D assets typically contain only geometric models and material appearance, lacking the mass, collision bodies, physical material properties, joint constraints, and object hierarchy information required for physical simulation.71% similarUnverifiedThe 3D proxy exists as an intermediate representation; the framework does not pursue photorealistic fidelity but seeks a balance between simulation physical accuracy and generation cost.70% similarUnverifiedThe core challenge of physical AI is bridging the gap between digital reasoning and physical execution, including understanding three-dimensional space, real-time sensor fusion, and built-in compliance with physical constraints.70% similar
