You can easily note a difference at the start-up of Catacombs, Cleopatra's Palaces levels in classic TRLE level set, or, in recent levels, King Arthur's Project (when jeep goes through underground area, you can easily spot how jeep's headlights affect wall textures).

The effect is not so obvious because generally TR has no dynamic lights applied to room textures, only static. It could be really awesome if TR supported bumpmaps on movables.
I wonder if it would work on the Flares or LED Light!?
