Install the asset library

1. Download and unzip "Used_Future_Utility_Kit_Blender.zip" anywhere you keep assets.
2. In Blender: Edit > Preferences > File Paths > Asset Libraries > "+" and pick the "blender" folder from the zip.
3. Open an Asset Browser editor and choose the library "Used Future Utility Kit": the 10 catalogs appear on the left. Drag pieces into your scene.

Demo scene

Unzip "Used_Future_Utility_Kit_Demo_Scene.zip" and open the .blend: it is the cover image scene, with camera and lights. Press F12 to render it in Cycles. Textures are packed in the file.

Material sliders

Select a piece and open Material Properties. Under Surface, each material shows its settings as sliders:

• Painted metal: Paint Color, Wear, Grime, Dust, Roughness, Pattern Scale, Edge Wear Width
• Hazard stripes: two stripe colours, Stripe Width, Wear
• Plastic, rubber: Color (and Roughness, Grime)
• Galvanized steel: Spangle Contrast. Rust: Rust Amount. All: Pattern Scale

Pieces share their materials (all blue paint is one material). To change one piece only, click the number next to the material name to make a single-user copy first.

Pipe generator

Drag "Pipe Run Example" from the "Generators" catalog into your scene, press Tab and move or extrude its points: the pipe runs straight between the points, with a long-radius bend at each point. Or select any curve (or a mesh made of edges) and pick Add Modifier > Used Future Utility Kit > Generators > UF Pipe Run (the asset library must be added in Preferences first).

Settings in the modifier panel: Pipe Size (DN50 / DN100 / DN150), Bend Radius, Bend Segments, Pipe Sides, End Flanges, Joint Spacing, Pipe Material. End a run 3 mm (gasket) from a valve or fitting face and the flanges bolt together. One path per object works best. Apply the modifier to get a mesh.

Pivots

• Pipes, fittings, in-line valves, ducts, cable trays, conduit: inlet face at the origin, run along +X. Place the next piece at the previous one's outlet.
• Wall pieces (boxes, panels, vents, signs, ladders): back face on the wall, centred, front toward -Y.
• Floor pieces (machines, gratings, step stands): centre of the base, on the floor.
• Gauges and tapped devices: process connection at the origin, rising +Z.
• Ducts and trays snap on a 0.25 m grid.

KIT OPS

1. Unzip "Used_Future_Utility_Kit_KPACK.zip": you get the folder "Used_Future_Utility_Kit_KPACK" with 10 categories.
2. Edit > Preferences > Add-ons > KIT OPS > KPACKS > Add KPACK path and pick that folder.
3. In the KIT OPS preferences, untick "Auto scale INSERT" (on by default), otherwise KIT OPS resizes each piece to the object under the mouse.
4. In the 3D View sidebar (N) > KIT OPS, choose a "UF ..." category, click a thumbnail and Add. Rotate wall pieces with Alt + mouse wheel while placing.

Game engines

• GLB is the most complete format (materials, alpha modes, emission). In Godot, a convex collision hull named -colonly imports as a static collision shape.
• FBX and OBJ reference the shared "textures" folder: keep the folder structure.
• Stickers use alpha cut-out, glass uses alpha blending.

PIECES.txt in the zip lists every piece with its family, size and triangle count.
