Luma blur black filter is not sharp

Hi there.

I try to make a grid of dots super blurry on the back and fully sharp on the front.
The thing is that the black filter width, even at 100% black is still blurry…

Any thoughts?

Hey @AcidBoy,

looking at it. Offhand it’s hard to tell how this should look. after all this is not a depth blur but just pixelbased - the kernel in the edge areas will be large as the second input has white pixels there…

But what also looks strange is the very pronounced vertical blurring in these areas.

will be back with some answers.
