Hey is there any way to use maybe a shader or script to control what part of a texture "reflects" light levels? Like if a blacklight was used the neon colors are vivid while the rest of the texture or wall is bland maybe even with a halo or glow effect only affecting the area desired?
 also was curious if there was a way to have light used in a way to reveal "hidden" things in a scene, say you have a flashlight object with colored lenses for it? Plain white light would show the basics, walls, floors, items. Pop on a colored lens like red and see bloody writing on the same wall you just looked at with the plain light, or see "ghosts" wandering around. Change lenses and poof you now in that wall see a door that was hidden ... scripting?? shaders?? dream??
