There are 2 files "hygge-corner-sofa.blend" and "hygge-corner-sofa_blender-3-3.blend". If you are using Blender version older than 3.4 use "hygge-corner-sofa_blender-3-3.blend" instead, becouse in fabric materials the new mix color node (old mixRGB) is not compatible with older Blender versions. Model is tested down to Blender 3.0.
