The sofa is mine but the rest of the scene except for the table is Andrew Price’s, the blender guru. The coffee table is by shocky and can be found here. The HDRI is from Greg Zaal. https://3dwarehouse.sketchup.com/model/b6457c273fca48f8b5b7c35a8e7396f2/dinning-room-table.
I saw a similar sofa to this by Mahmoud Keshta at cg arena. The photo and max tutorial may still be there. That is where I got the incentive to model this sofa. Thanks to Mahmoud.
