TL;DR of the post, generated automatically.

A modular sci-fi corridor kit for Blender, made in Cycles.

• Kit: 40 pieces (walls, doors, floors, ceilings, columns, pipes), snapping on a 0.5 m grid.
• Look: worn edges, screws, dirt in the corners, meant to feel used.
• Feedback: OP asks for notes, especially on the lighting.
