totjoss Posted September 29, 2020 Share Posted September 29, 2020 Hello ! I'm using the blur brush tool but is there a way to increase/decrease it's strength (like increasing a gaussian blur size), because in 4K resolution it's too light. And of course I tried changing the brush size/flow/strength but even at 100% it's not enough. Thanks in advance for your help.

AffinityJules Posted September 29, 2020 Share Posted September 29, 2020 You could try using the gaussian blur filter or live filter then mask out the bits that shouldn't be blurred? Quote Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe. These are not my own words but I sure like this quote.

No because it won't be a progressive blur, there'd be a "sharp" and "fixed blur" with alpha transition. Quote Link to comment Share on other sites More sharing options...

Perhaps lower the Hardness, Flow and Opacity of the brush to paint onto the Live Gaussian Blur mask layer, it should provide greater control.

thomaso Posted September 30, 2020 Share Posted September 30, 2020 You possibly run into a known bug with the handling of the graphic processing "Metal" in macOS, with "Open GL" you might get more blur affect.

No this is not what I meant, and I'm using Windows. 4 hours ago, Lee D said: Perhaps lower the Hardness, Flow and Opacity of the brush to paint onto the Live Gaussian Blur mask layer, it should provide greater control. Well... no, attached to this message is a sample of what I mean and why your solution would not work : - In Krita, the blur brush somehow spread more and more and the blur intensity is relative to the brush size, thus you have a great blur transition. - I just realized that Photoshop is equal to Affinity in this situation : no matter how strong, how big and how often I use the brush, the blur intensity will remain the same. - Your gaussian blur trick with alpha transition results to a very amateurish blur transition... And no I won't make multiple layers with different gaussian blur sizes on each, it would be damn complicated for nothing - I'd rather open Krita just for that effect and copy-paste it back into Affinity. So it seems there isn't any solution to this ? AffinityJules and thomaso 2 Quote Link to comment Share on other sites More sharing options...
AffinityJules Posted September 30, 2020 Share Posted September 30, 2020 It's rather strange that a program such as Krita can boast a far more superior blur brush effect than its loftier competitors? It can't be that hard these days to emulate such behaviour. Quote Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that.

evtonic3 Posted October 6, 2020 Share Posted October 6, 2020 This tool should be improved indeed. I mean if you can't get a blur brush right? Sometimes you need the simplest tool to be efficient. Not add layers to create this effect. Quote Link to comment Share on other sites More sharing options...
tom.s Posted October 8, 2021 Share Posted October 8, 2021 Oh god, another super basic feature that's missing. I've been trying to blur the edges of this mask for ages and it wasn't getting any more blurred. What even is the point in the blur brush if it can't blur anymore than like 4 pixels?!

mick560 Posted November 13, 2021 Share Posted November 13, 2021 I can never get the blur brush to work either on affin photo or designer, you would have thought there was a solution by now ? Quote Link to comment Share on other sites More sharing options...
R C-R Posted November 13, 2021 Share Posted November 13, 2021 I think the Blur Brush Tool is broken/buggy & has been for as long as I can remember. For one thing, there is no preview of the effect -- I just see an empty checkerboard pattern instead of the amount of blur I would get if I clicked to apply the brush. As it is, it does apply a blur, but it is just a very mild one that takes many strokes to have much of a visual effect, & after a few strokes it stops having any further effect. It is easy to see that it is not working like the Sharpen Brush Tool. mick560 and Ron P. 2 Quote All 3 1.10.8, & all 3 V2.4.1 Mac apps; 2020 iMac 27"; 3.8GHz i7, Radeon Pro 5700, 32GB RAM; macOS 10.15.7 Affinity Photo 1.10.8; Affinity Designer 1.108; & all 3 V2 apps for iPad; 6th Generation iPad 32 GB; Apple Pencil; iPadOS 15.7 Link to comment Share on other sites More sharing options...

Unfortunately, there are a lot of broken/buggy things in the Affinity apps competing for the attention of the developers. Some of them have been fixed in an update & then broken again in a later one as a byproduct of fixing something else. On top of that, at the same time they are trying to add new features (both user requested ones & ones they think users would like but have not specifically requested), which also can complicate fixing existing bugs & introduce new ones. Yet another complication is that everything has to work without causing problems on three different platforms (Macs, Windows, iPads) & in each of the Affinity apps. I think they are prioritizing all this as best as they can but inevitably it is not all going to happen as quickly as anybody would like, the developers included. mick560 1 Quote All 3 1.10.8, & all 3 V2.4.1 Mac apps; 2020 iMac 27"; 3.8GHz i7, Radeon Pro 5700, 32GB RAM; macOS 10.15.7 Affinity Photo 1.10.8; Affinity Designer 1.108; & all 3 V2 apps for iPad; 6th Generation iPad 32 GB; Apple Pencil; iPadOS 15.7 Link to comment Share on other sites More sharing options...
mick560 Posted November 13, 2021 Share Posted November 13, 2021 I understand and I am thankful for Affin Photo making a great product for the amount of money they charge, I can't even begin to understand how complicated it must be for the developer's.
