Built and checked like the real door: the four sections are joined by graduated hinges and run on rollers in the vertical tracks, round the curve and under the ceiling; the torsion tube carries the two springs on their cones, the drums and the cables down to the lower brackets. Handles and the side lock rods are included. The whole travel was checked without any contact between parts.The opening animation is included: the sections run up the tracks while the drums wind the cables. Made for house exteriors, garages, archviz and game scenes.

Contents (73 objects)

• 4 sections with ribbed outer faces (40 mm)
• Lower rail and seals
• Jambs and top seal
• Vertical and horizontal tracks with the curve
• Track hangers
• Section hinges and roller brackets
• 10 rollers
• Torsion tube with bearings
• 2 torsion springs with their cones
• 2 drums and 2 cables
• Outside and inside handles
• Lock rods and latches

Animation

• Frames 1-240 at 24 fps: the door rises (1-100), stays open, then comes down (140-230).
• The sections roll on the tracks hinge to hinge; the drums and the torsion tube turn about 6 times and wind the cables, whose straight runs follow the lower brackets.
• Hierarchy: the centre bearing bracket is the root; each section carries its rollers, hinge halves and hardware.

Model

• 73 objects, 191,038 triangles (101,352 faces), 96,465 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 2.626 x 2.030 x 2.650 m.
• Pivots on the real axes, moving parts parented; named parts grouped in collections (01_Frame_Tracks, 02_Curtain, 03_Springs_Cables).

Textures (PNG)

• 2 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.
