Rectangular wool rug.

The pile is implemented by the displacement map. For close-ups I recommend setting Screen size: 0.5px in Render Setup > Performance > Displacement for medium and long-range plans this value can be increased to 2-3px.

The large file size is due to the use of 6K textures.

File Format:
– 3ds max 16 corona render
-OBJ
-MAT

For Corona render it is recommended to install a version of at least 1.5 since the glossiness of materials is configured with PBR in mind.
