Gaussian blur has a box around it

I've encountered a problem with a gaussian blur that I've never seen before in the new update of Illustrator. When I put a blur on an object there's a border that cuts off the effect. You can see in my screenshot here.

In the Document Raster effects options there is a setting "Add"

Try to increase it.

Additional information:

In the 'Document Raster effects settings', make sure to select the Transparent option under Background - do not choose 'White'.

Thank you for that. Mine is set to transparent and it’s still generating a white box around the text instead of just the blur area. :(

Hello ​@Sawyervg4 

 

I’m sorry to hear you’re having similar trouble with Illustrator. Could you confirm the exact version of the OS/Illustrator installed, and share a sample file along with screenshots of the problem, so we can better assist you?

 

Looking forward to hearing from you.

I was having the same issue in Illustrator CC. I already had 'Transparent' selected and tried selecting 'Anti-Alias' but I was still running into the issue. Then I changed the 'Add _[36 px]__ Around Object'. I increased mine from 36 > ~200 px and it seemed to work for me.

Go to Effect > Document Raster Settings > Add ____ Around Object: increase the pixels until the edges don't show.

For After effects users:

To remove the 'box limitation' when trying to add a gaussian blur to an object, unselect 'Repeat Edge Pixels'

By @Oli27331267afm6

 

This is the Illustrator forum. The question is not about how to do it in After Effects.

Solved : Go to Effects/ Document raster effect settings  - and select the 'anti-alias' box.

That doesn't seem to help. I don't want to rasterize my blurs because I always need to edit them. But even trying it, it's still cut off on the edges. This is a blue with adding 80px around the object
