Hi I would like to reveal a message on a mesh when shined by a flashlight. What can I do to achieve this material? I know some people are trying to use 2 normal/spec maps but how to reveal only the letter being shined?
This is the example
Firing a trace line from the player camera and hide/unhide the object seems like an alternative but is there a better way of doing it? If possible I want the problem to be tackled from the material it self.
