Substance released a new update to Alchemist, and it has an interesting feature that uses AI to take an image and create materials from it. I used it here for the carpet, and composed this scene with models I had from a previous life.
this image is using the Rhino interior environment, and one panel light set to inverse squared falloff. I had the sun on but set to a very low intensity (like .1)
The carpet is a material from Alchemist, brought in as a PBR using the material from image files import. The rest of the materials are simple default materials.
here is a link to a tutorial for alchemist.
