Couch and light scene

This is a scene including a couch (based off of a particular [IKEA sofa](https://www.ikea.com/gb/en/p/landskrona-4-seat-sofa-with-chaise-longue-grann-bomstad-black-wood-s09032412/)), a lamp based off of a [Stepp floor lamp](https://stuartlambledesigns.com/product/stepp-floor-lamp/), and a wood floor material that I created myself. Originally this was made for Unreal Engine, and used materials that combined two colors and a mask to set the color for the couch fabric and the couch treads. I included those masks so you can do the same in whatever engine, or 3d application, you're using. Sketchfab doesn't have that kind of functionality yet! 😉 Also the wood floor uses 8192 x 8192 textures, and the original format was a .png. Unfortunately the basecolor texture was above the Sketchfab file limit, so I had to convert it to a .jpg. The loss of quality is minute, but if you really want that original .png I can make arrangements to supply it to you.
