Gradient that goes with shape edges

[Zellu]

Hello there,
I want to achieve gradient effect like this:

Like only the edge of the gradient goes to the full transparency. Something like irregular radiant gradient 🙂
The funny story is, this is my own work from the beginning of the year. I remember it was super simple to make, so I didn't bother to save url tutorial or the way I did this.  Like it was just selecting one option.

Now I'm searching for a way to do this. Can anyone help? 🙂

It looks like a Gaussian Blur has been applied (Filter > Blur > Gaussian Blur...).

Like Myra says, Gaussian blur is probably applied. Another way you can achieve this is by selecting the object>select >inverse>select>modify>feather and delete to desired effect.

Thanks for your replies!

After two more hours I've found the solution 😄

After creating a shape (it can be even irregular one), you just need to add layer effect > stroke, choose gradient one and type would be "broken shape" (I don't have english version, may be slight different) - you probably won't find that gradient option anywhere else.

Well, old gaussian blur also will do the trick. However, this is way more flexible and can produce more complex effects (but I know my ask was pretty simple :))
