A Sketchfab model can be a good starting point for a browser game only after rights, file integrity, material references, scale, polygon weight, texture size, and target runtime are checked. Do not assume a marketplace preview equals WebGL readiness. Upload the actual package, record source_tool=sketchfab, inspect failed_upload_reason if parsing or textures fail, optimize for Three.js or playable delivery, then export GLB, USDZ, FBX, or OBJ notes that match the real workflow.
