Hey, i would like to create the following feature and i could really use your experience to maybe give me a hint where to start and what i could do better. My game is in first person. I want to create a scan-mode, where the player equips scanning gear and then can see things that where hidden before. Let me try to illustrate that with a mock-up made from content that is not by me. ( See Skyscan.png ) My idea would be: Add a new camera with a color-invert or LUT replacement-shader and make it render on a texture. Show the texture on a canvas with a mask to get only that ellipse-part in the middle. put the symbols that shall only be seen in scan mode on a layer that is not rendered by cameras except for the scan camera. I wonder if render to texture is a good idea, it sounds like somethings that could cost a few fps. Is this a valid path to take or am i missing something or trying something in a really bad way? Thanks for spending your time on reading this!
