What you get

• .blend (Blender 5.1, Cycles): one asset library — every model is a drag-and-drop asset with its own preview, sorted in catalogs by system, type and variant. Procedural materials, real scale in millimetres.
• FBX (mm), OBJ+MTL and GLB (metres): one file per model, flat PBR materials (base colour, metallic, roughness), UVs on every part.
• Every model in two versions: High for close-ups, Low for façades and game scenes (54 files per format).
• Clean English part names (Frame, Sash, Glass, Hardware, Sill, Shutter_Box, Shutter_Curtain, Guide_Rails…), so parts can be hidden or re-textured.

How to use

• Blender: unzip, open the .blend and drag the models from the Asset Browser, or add the folder as an asset library to use them in any scene.
• Other software: import the FBX, OBJ or GLB file of the model you need.
