Hi, we have gotten to a point in our game where we started going deeper into mechanics, and we would like to give the player a uv lamp, which he can use to uncover secret writings and such.
Any ideas how we can create a material which can be revealed by shining a specific light source on it?
Help is greatly appreciated, thanks in advance.
Hey there @DarkZero02! Welcome back to the community! So generally you’re going to want to do a bit of a reversal of what many people use to hide objects when a world space object comes near it. You’d use the technique from this video, but instead of hiding or dissolving something near an object or player, you’d overlay your hidden writing (likely in the emissive). The video’s a bit long, but it’s necessary to watch from the beginning to understand why the nodes work.
