How to create a Time Warp/Screen Scanner Pro/Slit Scan lens

I won't go over the complete process to fully recreate the Screen Scanner Pro lens (because that wouldn't be very cool because I didn't create the lens), but I will teach you how the effect is achieved.

In short, all you have to do is change the Clear Color on the render target to "None." That's basically it. I go over how to set everything up and kind of why this works in my tutorial, but that is the secret - it is just a lesser known/utilized feature of Lens Studio.

You can find the written version of the tutorial here which includes a link to the video version.

You can do so much more with this knowledge than just copy the aforementioned lens, so please create something cool and original. We already have the Screen Scanner Pro, so let's see what you can make. You can use masks with different shapes or multiple scanning lines, you can create fake motion blur, you can use crazy random masks for a glitch effect, the list goes on and on.
