Additional Notes & Comments:	Not set

Steps to Reproduce

1. Get Lamp from lights out event
2. find a metal door
3. Compare visual inconsistency on door

Explanation

During the Lights Out event on Léry's Memorial Institute, the ray tracing on the lamp rays interacts incorrectly with the metal doors. The Blinn-Phong shading is inconsistent, resulting in incorrect light reflections and artifact shadows rendering on these specific metallic surfaces.
