Every surface shimmers with mother-of-pearl light. The walls breathe iridescence. The tide pools glow from within.

Nacreous Realm is a world morph that transforms any environment into a pearlescent dreamscape. Architecture takes on the luminous quality of abalone shell — swirling colors that shift with viewing angle, soft internal glow from bioluminescent accents, and surfaces that feel both alien and impossibly beautiful.

Where other world morphs replace materials, Nacreous Realm refracts them. Stone doesn't become something else — it becomes nacreous. Columns shimmer with opalescent color shifts. Crystal formations catch and split light into rainbow refractions. The effect sits somewhere between deep-sea bioluminescence and the inside of a seashell.

Trigger Word
Use nacreousrealm for strongest effect. The morph also activates at higher strengths without the trigger.

Recommended Settings
Trigger: nacreousrealm Strength: 0.7–1.0 (recommended: 0.85) Dark environments showcase the bioluminescent glow best. Interiors with lots of surfaces give the morph maximum material to work with.

Weight Guide
0.5–0.6: Subtle pearlescent highlights 0.7–0.8: Clear nacreous transformation, bioluminescent accents 0.9–1.0: Full immersion — every surface pulses with mother-of-pearl
