No, seriously...this is by far the most epic - and by epic, I mean legendary, incredible, amazing - failure I've ever had. Don't ask me how or why, but, for some reason, changing the size of my diffuse texture to 1x1 caused...no, not a scene of solid-colored objects as I had hoped...no, not a failure message from D3D...no, not a crash...but rather, a mind-blowing scene of recursion. Of course, it should have been obvious to me that resizing a diffuse texture would...cause it to be replaced by the primary render target!?!?
This is by far the coolest glitch that has ever befallen me. Every surface displays an exact replica of that which is rendered on the screen (and it also happens that I had SSAO and DoF turned on at the time of the glitch...so it's a rather beautiful setting for a glitch!). Good example of recursion, yes? Also quite a trip.
But seriously...why didn't I ever think to do this intentionally???
