Hi Guys, So I have come up with a specific idea in my mind for an event that is going to happen in my game but I need to know a few things before I attempt to try and create it. Basically I want footprints to start walking across my floor in my map (wet footprints to be specific) but I want this to be revealed in front of the player as if there is an invisible person walking in realtime and all they can see is the footprints of the water on the floor. I was wondering at first how to achieve this then I thought the decal system in Leadwerks may just make this work. My questions are: Is there a way to reveal decals in real time (some sort of way to mask them and then move that mask, just a thought). If decals isn't the answer, what tools in Leadwerks would be able to achieve something like this? My first thought would be to get a character and put an invisible material on that character and use decals for the footprints and somehow reveal them that way. Right now all I have is idea's but nothing seems to make me think that it would work haha. Thanks.
