What helps during handoff?
For STL to GLTF, Copilot 3D prioritizes geometry, hierarchy, UVs, normals, object names, and material references that make cross-tool handoff easier to verify.
Advanced PBR networks, animation, rigs, and custom extensions can still require downstream checks. Use the result as a clean exchange file before production import.
