55 independent static industrial assets: pumps, motors, electrical controls, vessels, valves, piping, access modules, structure pieces and lights. The complete set contains 252,774 triangles for one instance of every product, excluding repeated scene instances, collision hulls and presentation architecture. Individual products range from 132 to 13,824 triangles. No rigs, animation, operational pumps, scripted valves, LODs, navigation or gameplay are supplied.

The source Blender files retain editable polygon meshes and fixed export triangulation. FBX and OBJ are triangulated. Five original PBR PNG maps per product (275 files): BaseColor, Roughness, Metallic, Normal and AO; 5 model sets at 1K, 45 at 2K and 5 at 4K. BaseColor is sRGB; data maps are linear. Source normal maps are OpenGL +Y. Each product has one unique UV atlas in 0–1, without UDIM.

Library_Overview.blend displays all 55 items at their original physical metre scale with equal free gaps. Pumping_Hall_Demo.blend is a decorative pumping-hall assembly. Extra floor, walls, window panes, beams and support blocks are presentation architecture, not additional unique library models. Other compositions may require transform adjustment: seller-edited pieces are not claimed to be a universally interchangeable pipe-grid system. Original pivots are retained: floor props generally use base pivots, mounted parts can use central or mounting pivots. No automatic socket snapping is supplied.

Open a source/*_stage2.blend or export/*.blend to edit an individual product. Keep its sibling textures folder beside source/export when unpacking. FBX/OBJ materials require checking importer conventions; run the supplied source/Apply_PBR_Maps.py on selected imported meshes in Blender to configure data maps as Non-Color and restore the separate AO preview. For a game engine, connect AO to its occlusion input rather than adding it to the BaseColor image.

Unity: Unity 6000.6.1f1 / URP 17.6.0, 55 prefabs, static MeshColliders, Overview and Demo scenes. Unreal: UE 5.8.3, 55 Static Mesh assets, simple convex collisions, Overview and Demo maps. Only the tested Windows editor versions are claimed; player builds, mobile/VR and performance targets are not verified. No paid third-party plugin is required.
