applying mask to smart object filter

[bartonlew]

I am trying to apply a linear gradient to a Smart Filter in PS.  The instructions I found online were as follows:

1. Convert the Background layer to a Smart Object (with the layer selected, go to Filter > Convert for Smart Filters)
2. Apply the Gaussian Blur to the Smart Object (it will become a Smart Filter)
3. Select the Smart Filter Mask (it'll show up below the image thumbnail and the filter in the Layers panel
4. Select the Gradient Tool and draw your gradient on the mask (black conceals, white reveals)

Screenshot 1 shows my results after adding the Layer Mask.  Have I done this correctly?  Screeen shot 2 shows my result after drawing the gradient - which reveals the canvas.  I tried making the foreground color both black and white and it didn't make a difference (meaning canvas still showing, not what I want).

Hi @bartonlew you're applying the gradient to the layer mask which will affect everything including the image.

If you only want to affect the Filter, click the mask on the Smart Filter portion below and apply your gradient there.

That will mask the effect/Filter fading it over the image.

Of course.  Thank you so much.
