A 3D model file converter for game assets should not just rename formats. Before converting STL, OBJ, FBX, GLB, GLTF, USDZ, scan, marketplace, or AI-generated files, inspect whether the model loads, whether scale and pivot are usable, whether materials and textures survive, how heavy the mesh is, what the target engine needs, and why upload or conversion failed. Then choose GLB for web delivery, FBX or GLB notes for engines, OBJ for interchange, or USDZ for AR when the inspected asset can support that handoff.
