Built and checked like the real shutter: the slats hook into each other and wind on the barrel in a spiral, the base bar with its seal closes on the floor, the curtain runs in the guides with their wear liners, and the drive motor carries the chain wheel and the hand chain loop for manual opening. The whole travel was checked without any contact between parts.The opening animation is included: the curtain winds onto the barrel and back down. Made for warehouses, workshops, shops, archviz and game scenes.

Contents (50 objects)

• 38 galvanised slats with wind locks
• Base bar with seal and shoes
• 2 side guides with wear liners
• Barrel with straps
• 2 end brackets
• Drive motor with chain wheel
• Emergency hand chain loop
• Hood

Animation

• Frames 1-240 at 24 fps: the curtain winds onto the barrel (1-100), stays open, then unwinds (140-230).
• Each slat follows the coil spiral and the guides; the barrel turns about 2.6 times; the base bar stays level.
• Hierarchy: the hood is the root; the slats, the base bar and the barrel are its children.

Model

• 50 objects, 370,144 triangles (190,308 faces), 185,398 vertices in total.
• Clean polygon models: quads and triangles, no n-gons, closed shells, sharp edges with weighted normals.
• Real-world scale in metres, centred on X and Y with the lowest point at Z = 0 (closed); overall 3.518 x 0.589 x 3.620 m.
• Pivots on the real axes, moving parts parented; named parts grouped in collections (01_Guides, 02_Curtain, 03_Barrel_Drive).

Textures (PNG)

• 3 PBR texture sets at 4096 or 2048; non-overlapping UVs, one texel density per set.
• BaseColor, Roughness, Metalness, AO and Normal maps (OpenGL and DirectX) for every set.

Formats

• FBX and glTF 2.0 with the animation, OBJ + MTL (static) and Blender 5.2, each format zipped with its textures; the textures also come in their own zip. No plugins required.

Notes

• Brands on the parts are fictional; lighting, backdrop, walls and cameras are not included.
