DESIGN VARIANTS AND OPTIMIZATION
The chair, sofa and armchair upholstery shown here is a deliberate architectural finish variant.
Original brown/black base-color maps are omitted for the clean variant; source normal/roughness detail
is restrained and new cloth/frame colors are assigned in code. The result is not a manufacturer
finish specification, physical replica, or a claim that the source author approved this design.
Source image files remain unchanged. Chair geometry was reduced from 22,013 to 4,401 triangles.
Potted Plant 02 preserves all 10,692 leaf triangles; hidden soil and pot geometry were reduced.
The full-detail plant has 12,527 triangles. Dirty Carpet and White Plaster 02 contribute restrained
surface maps; their worn/mottled albedos are not the default room finishes.

OFFICE CHAIR
Office Chair by nisu (author listed by OpenGameArt).

Author profile: https://opengameart.org/users/nisu
Original project: https://www.3dmodelscc0.com/model/office-chair
License: CC0-1.0; full text: licenses/CC0-1.0.txt
Original FBX/PBR converted to glTF with 1K textures and normalized to 1.05m height.
The 4,674-triangle source geometry and original fabric/plastic appearance are preserved.
This asset does not use the clean upholstery recoloring described above.

Carpet finish update: original Dirty Carpet texture contributes luminance-only weave detail
through a runtime shader (0.84-1.16 modulation); its brown/olive hue is suppressed.
Original image files remain unchanged.

Modifications: PBR maps resampled from4K to1K; original mesh/proportions retained; 12 instances placed using original conference coordinates; unique UV1 atlas added for split baked diffuse lighting.

Source color and OpenGL normal unchanged. Roughness remapped to .82+.14R. .40m material repeat is a design assumption. Woven source used as loop carpet approximation, not a claim of installed product.
Wall and ceiling: authored uniform manufactured paint/acoustic finish; no scanned-surface claim.

Geometry and index streams are losslessly encoded; no quantization or additional geometry reduction.
Clean Fabric045 and authored paint finishes also apply to the floor overview.
