This model showcases extensive technical detail on its high-bypass CFM-56 style turbofan engines — providing authentic retro details for professional creative pipelines.\n\nSourced straight from master engineering-grade CAD/NURBS surfaces, this asset delivers mathematically perfect skin transitions, immaculate fuselage curvature, and smooth specular highlights. Because this is a fully original, fictional layout, it functions as an entirely non-IP asset. You can safely deploy it in commercial video games, flight simulators, retro flight titles, cinematic films, and real-time visualization projects without any trademark licensing fees or legal restrictions from real-world civil aviation manufacturers.\n\n---\n\n## All Formats Are Fully Textured (Livery Baked In)\n\nThis asset package is completely production-ready out of the box. Every file format included in this bundle features high-quality textures and vintage airline livery maps baked flawlessly from the master aerospace CAD files:\n\n* Real-Time Formats: Optimized low-poly meshes (OBJ, GLB, GLTF) feature a pre-baked, engine-ready livery texture map. Ready for direct, drag-and-drop integration into Unreal Engine, Unity, and real-time web-based rendering workflows.\n* Vertex-Color High-Poly Master: The premium master setups (PLY and native Blender .BLEND configurations) feature rich, vertex-based color values calculated directly from the original CAD source for high-fidelity visualization with zero external texture node dependencies.\n\n---\n\n## Geometry and Engineering Notes\n\n* CAD-to-Mesh Perfection: Clean, highly predictable polygonal topology generated directly from smooth NURBS source geometry. Optimized for real-time performance and high-performance engine rendering at approximately 39,770 triangles.\n* Organic Surface Flow: Absolutely zero surface wrinkling, normal pinching, or shading artifacts around complex geometric intersections, such as the individual wing-mounted turbojet pylon mounts, historic engine nacelle intake cowlings, and classic low-slung conventional tail surfaces.\n* Flexible Utility: An ideal baseline asset for custom hard-surface concept development, custom historic livery skinning, or interactive media modifications.\n\n---\n\n## Included Formats\n\n* 3D Real-Time (Fully Textured with Livery): OBJ, GLB, GLTF, PLY, FBX, ABC\n* CAD Engineering Data: STEP AP214, IGES, CGR, X_T, X_B\n* Native Source File: .BLEND (Blender 3.6+ Cycles-compatible layout)\n* 3D Printing Ready: STL, 3MF (Engineered to scale reliably across various sizes for FDM and resin printing display models)\n\n*Note: This model is focused entirely on premium geometry and baked liveries; it does not include rigging or animations.*","imageAlt":"DC-8-10 CFM Style 1950s Jetliner - Custom Quad...","url":"https://www.cgtrader.com/3d-models/aircraft/commercial-aircraft/dc-8-10-cfm-style-1950s-jetliner-custom-quad-engine","isCLDApplicable":false,"isSaleOffApplicable":false,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/137oqrnb7v6q23h9047iha23s3z1/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/Screenshot%202026-06-03%20204824.jpg","gridUrl":"https://media.cgtrader.com/variants/137oqrnb7v6q23h9047iha23s3z1/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/Screenshot%202026-06-03%20204824.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-models/aircraft/commercial-aircraft/dc-8-10-cfm-style-1950s-jetliner-custom-quad-engine","isCgtVerified":false,"types":{"printReady":false,"animated":false,"pbr":true,"rigged":false,"lowPoly":true}},"metaverseFormatsList":[{"id":21,"name":".blend","is_native":true},{"id":117,"name":".gltf","is_native":false},{"id":210,"name":".x_t","is_native":false},{"id":12,"name":".obj","is_native":false},{"id":104,"name":".abc","is_native":false},{"id":189,"name":".ply","is_native":false},{"id":72,"name":".stp","is_native":false},{"id":29,"name":".ige","is_native":false},{"id":129,"name":".3mf","is_native":false},{"id":5,"name":".fbx","is_native":false},{"id":51,"name":".stl","is_native":false}],"categorySlug":"aircraft","subcategorySlug":"commercial-aircraft","categoryTitle":"Aircraft","subcategoryTitle":"Commercial","schemaImageUrl":"https://img-new.cgtrader.com/items/7149603/64118ca28e/dc-8-10-cfm-style-1950s-jetliner-custom-quad-engine-3d-model-64118ca28e.webp","saleOffDiscount":0,"eligibleForSubscription":true,"subscriptionSubscribed":false,"subscriptionPotential":true,"subscriptionTierBand":"essentials"}},{"id":"7156026","type":"listingItem","attributes":{"id":7156026,"title":"DC-8-50 CFM Style 1950s Jetliner - Custom Quad Engine","price":7.89,"description":"3D Jetliner Model Overview\nThis premium 3D asset is a fully original, fictional narrowbody passenger airliner concept.
