A modular industrial piping kit built around NPS 4 Schedule 40 pipe (114.3 mm outside diameter, 6.02 mm wall). Use the ready-made assembly as it is, or take parts from the catalog and build your own pipe runs for factories, plants, mechanical rooms and industrial game levels.

Created in Blender using procedural modeling with Python scripts.

WHAT'S INCLUDED

• Assemblies: a ready-made piping layout with two globe valve lines, a 45-degree offset and a tee branch. 402 separate parts (pipes, fittings, flanges, gaskets, valve parts, stud bolts and nuts). Every part's origin is at the bottom center of the whole layout (world origin), so everything stays in place when imported.
• Catalog: 10 ready-to-place parts, one object each, pivot at the bottom center of each part:Pipe 0.5 m, Pipe 1.0 m, Elbow 90, Elbow 45, Tee, Raised-face flange, Blind flange, Gasket, Flanged globe valve, 8-stud bolt set (M16)

FEATURES

• Real-world scale in meters (assembly: 3.16 x 1.26 x 0.98 m)
• Quads and triangles only, no N-gons; transforms applied; models sit on the origin
• One material with a 4096 x 4096 PBR trim sheet: Base Color, Metallic, Roughness, Normal (OpenGL), PNG
• Clean naming (Asm_ / Catalog_ prefixes); no cameras, lights or empties in the files
• Not rigged, not animated

LODs (both included)

• LOD0: Assemblies 130,386 polys / 246,270 tris / 123,013 verts; Catalog 35,215 polys / 67,258 tris / 33,481 verts
• LOD1: Assemblies 85,717 polys / 160,616 tris / 80,175 verts; Catalog 27,607 polys / 52,931 tris / 26,312 verts (bolts, nuts, handwheel, valve body, tee and blind flange reduced)

FORMATS (one zip per format, each with Assemblies and Catalog in LOD0 and LOD1)

• Blender 5.3 (.blend), FBX (binary), OBJ + MTL, STL, glTF 2.0 (.gltf + .bin), GLB, USDZ - all in meters
• Textures: separate textures zip (4 PNG). GLB and USDZ have the textures embedded; the glTF folder has its own copy.

IMPORT NOTES

• Unzip the textures zip next to the .blend / .fbx / .obj files so that the textures folder sits beside them.
• FBX / OBJ: Y-up, -Z forward, meters.
• Unreal Engine: the normal map is OpenGL - enable Flip Green Channel. Turn sRGB off for Roughness and Metallic. Import LOD0, then add LOD1 with Import LOD in the LOD Settings panel.
• Some importers do not connect the Metallic and Roughness maps automatically; assign the included maps if needed.
• STL is geometry only (no textures). The model has not been prepared or tested for 3D printing.

TECHNICAL NOTEPipe outside diameter and wall thickness follow ASME B36.10M (NPS 4, Sch 40). Flanges are modeled on ASME B16.5 Class 150 NPS 4 proportions (230 mm outside diameter, 156 mm raised face, 8 x M16 stud bolts). Elbows, tee and globe valve are modeled for visual use and do not follow ASME B16.9 / B16.10 dimensions. All values are modeling targets, not engineering documents or certification.

The studio background and lighting in the preview images are not included.
