Thank you for your attentiveness. Yes, of course, this is a concept. Therefore, I insert some ready-made fragments-photos from the Internet that are suitable so as not to waste time on modeling. All the doors are made this way, these are the photos on the boxes, and the shelves are the same. The design is going on in another program at the same time while the render is loading. I try to distribute the forces in the project. Glass partitions are modeled entirely in SH3D walls, here you need to do this when there is a translucent glass. I use SH 3D as a replacement for visualization programs, not for design.
My old processor has 4 cores, if I'm not mistaken)). Probably it's not enough, but how much is there..
