Stop Motion Camera Effect

Unity Engine
1

I’m trying to achieve a stop motion effect similar to those claymation movies of the 50’s. I seem to be running into a problem though.

I’m taking a “snapshot” of the scene then waiting till enough time has passed (framerate speed), then replacing that snapshot with a new one… over and over.

The script seems to be working, BUT there is kind of a stuttering effect. It seems as if the image that is getting snapshotted, is blank. (All I see is grey)

Here is the script. Let me know if you guys notice anything funky. Thanks!

var frameRate:float;

private var nextFrame:float = 0;

function OnRenderImage(source:RenderTexture, dest:RenderTexture){
    if(Time.time >= nextFrame){
        Graphics.Blit(source, dest);
        nextFrame = Time.time + (1/frameRate);
    }
}

You can do it with OnGUI function, take a screen snapshot and use GUI.DrawTexture. Update the image every 0.2 seconds and display it again. And everything else behind the image is working normal.

Thats an good idea.

However, the script that I have above should be doing that exact same thing. O.O I took a deeper look into it and it seems that the “RenderTexture” isn’t getting saved and this causing a stuttering effect. It looks as if nothing is being displayed during the time when it should be. D:

Could you not just force the game into a low fps instead of relying on some trick?
