Tilt-shift with Iray Camera?

With all the fun new Iray camera settings, including shift, I'd thought about doing a tilt-shift image. I couldn't see a way to do it, however. Is there something undocumented that might allow this? Or does it have to be done in post?

    This comes up from time to time, with some people wanting "tilt-shift" as discussed on that Wiki page, or the more traditional perspective correction as is common in architectural photograpgy. Either way, I don't think there's a feature, undocumented or not, for this.

    "Tilt-shift" is supremely easy in Photoshop, and can be done with a radial gradient mask against a gaussian (or other) blur filter. Its very controllable and doesn't involve altering the underlying image, so you can retweak as much as you need. Probably take less than a minute to set it up. PS would also do the perspective correction, but not without a loss of pixel resolution, depending on the perspective fix, so it's important to overscan the render in order to keep quality.

    Shift is supported, I don't think tilt is.

    Thanks. I knew it could be done in PS, but I wasn't sure how close that got to the real effect.
