A very typical effect – there’s a big explosion, and the whole scene (i.e., the entire camera view) flashes white for a few frames.
(This is also trendy with many editors of TV commercials … when you change shots you “cut through white” and it gives a sort of trendy white flash effect with the cut.)
To alternately explain what I mean, it’s like when you get a bright flash (the whole scene) indicating “someone took a photo”.
I’ve tried a few solutions like adding a cheesy white 50% plane in front of the lens, but I guess there’s probably a conventional way to do this I don’t know about?
Could this relate to Image Effects? (is for ipad only BTW)
Surprisingly couldn’t find anything like this using the search function. Thanks !
Use a 2x2 pixel white texture on a GUITexture, set to cover the entire screen–position (.5, .5), scale (1, 1), 0 for pixel inset values–then fade it out over time. (Like with this.) Also, disable the GUITexture when it’s not actively in use…100% transparent pixels covering the entire display is really quite bad for fill-rate.
If you use an HDR image, you might get some blooming that looks more like overexposing the shot, Hollywood style. Don’t know if you could do that on mobile though.
iTween has a section of scripts called CameraFade (CameraFadeAdd, CameraFadeFrom, etc.). You could just use that with a small white texture and fade it in or out as needed.
