Straight walls kill immersion. When you dig along standard north-south or east-west coordinates, your eyes register the predictable repetition immediately. In real geology, water, tectonic pressure, and mineral composition carve erratic paths through bedrock. A flat wall built purely of stone reads as artificial human construction, even if your intent was to maintain an untouched, rugged aesthetic.
Diagonal building techniques solve this perceptual flaw. When a wall cuts across the coordinate plane at an angle, the stair-stepping pattern of individual blocks forces the rendering engine to cast dynamic, micro-level shadows. Instead of a single, uniformly lit plane, the surface gains tactile rough edges. This simple shift provides the structural foundation for high-end aesthetic underground bases, bridging the gap between raw world generation and intentional architecture.
