How to fade a blur from full blur to no blur across a linear space

I would assume this is relatively easy, but not quite seeing it.  I would like to apply a gausian blur to underlying layers such that it is very blurry at one end of a reectangle, and no blur at the other end, fading between much like a gradient.

So far, I've had no luck trying to dial in various combinations of adjustment layers with gausian blur effect along with applied gradients.

thx.

Using a mask or track matte on an adjustment layer will limit any effect, but you'll have to pre-compose the track matte, the adjustment layer, and the rectangle so that the effect does not apply to all of the layers in the comp. I created a simple text box, added it to a new comp, created black to white gradient fill, put an adjustment layer below it, and got this:

The screenshot shows you everything I did to limit the Gaussian Blur effect using the gradient as a luma track matte.

Great trick! Worked. Could someone make this as a plug-in or a script?

Not natively possible. There is no way to modulate the blur kernel. If that's really what you want, your only option is the camera lens blur with a custom faux depth map. Otherwise buy RevisionFX SmoothKit. It has exactly the kind of Gaussian Blur effect you are looking for.
