Furniture 3D models often appear dark due to three main issues: insufficient scene lighting, incorrect material reflectivity, or low-quality texture maps. Insufficient lighting—like missing key or fill lights—leaves the model unilluminated, with no light to highlight its shape or details. Materials with low reflectivity absorb too much light instead of bouncing it, making the model look flat and dim. Low-resolution textures reduce light interaction, so even with good lighting, details (like wood grain or fabric) appear dark. To fix it, start by adding or adjusting lights. If that doesn’t help, lower material roughness (to reflect more light) or use higher-quality textures—simple tweaks that usually resolve darkness quickly.
