Preserve the untouched STEP assembly asset and record texture paths before changing geometry, materials, textures, hierarchy, or metadata for texture dependency map.
For STEP assembly texture dependency map, Keep the sample file, application versions, import and export settings, screenshots, logs, and fallback format. Product, marketplace, regional, and compliance decisions still require the responsible specialist.
