Making of "Stylish Bedroom" in Blender

Final render

Wireframe view.

Scene seen by camera 1 in Blender viewport.

Textures view

Highly detailed sofa model

Wireframe of sofa seat.

Sofa model consists of 3 elements.

It was textured in Substance Painter, so each model is unwrapped with unique UVs.

The only light in the scene is provided by Sky Texture in World settings. We desaturated it with Hue / Saturation node.

To increase speed of rendering we placed light portals in windows.

All light portals selected.

Building "exploded" - you can see individual meshes. It's better from texturing perspective to separate surfaces and gain texel density during texturing. This way we get more details on each surface.

Wall (and all other opaque and non-emissive models) uses standard Principled BDSF shader
