Thank you but I won't use AP 1.10.5 anymore because some important tools are not working correctly and Serif decided to abandon its updates: 1: I just ran AP and this is the result of the first strokes: pretty white borders but I don't want that effect, it's a bug. 2: Bad import of abr/photoshop brushes (it's an unfinished feature). 3: Brush "Blend modes" do not work as expected and some important "modes" simply do not exist, not even an single alpha pixel comparison. (most other apps of this kind have it, it's a must) 4: The Pencil brushes are not usable because of Pt.3 and btw, the pressure control becomes unstable and difficult to control when combining textures. 5: The recovery file works correctly, thanks, but AP crashes too often when adjusting value parameters. ... I don't remember more issues right now.

Yes, same problem here. The brush engine seems unfinished and will never be completed, probably due to bad concept so, I'm pretty sure the ABR brush importer will never work as expected, contrarily to what their false advertising tells. I feel sorry for all the customers that purchased Affinity Photo, thinking it was somewhat comparable to PS.

I purchased 1.10.5 version of AP some months ago, this year. How is it possible I have to pay again for getting just one or two new features I may need one day? Totally non-sense. Think a bit more, please! Then, the trial of only 30 days (Clip Studio offers 6 months) is not fair because when a user can't test it due to force majeure or being too busy, when the trial expires, he won't have more opportunities to download a new trial version. In my case, since I couldn't test it thoroughly enough, I purchased the software, convinced it would work as any commercial application of this kind, but after a time I discovered the brush engine is totally unusable for sketching due to unstable pressure sensitivity and lack of necessary blending modes. Sorry to be franc but this application (Affinity Photo V2) is not ready to be sold with such a brush that produces dirty artefacts and doesn't even import correctly Photoshop brushes (abr); even free applications have better brush engines. To all the unhappy customers who think Serif business model is not fair, please comment if you have in mind a convincing solution. (Sorry if my poor English expressions sound a bit aggressive, it's not my intention)

Thanks @Lee D Current brush overlapping method is good for simulating a felt pen or an airbrush but, as @polymath said, alpha replacement method is necessary for getting more accurate digital shadings, based on pen pressure. A well conceived brush engine should allow the combination of both methods in order to simulate almost any tool, I mean, a color blending mode like mix, add, multiply, lighten, colorize, etc. and, separately, an alpha blending mode like add (current Affinity Photo default method), replace, replace if higher, etc. The alpha blend mode can easily be added to the current mode list as "replace highest alpha", "most opaque" ("replace" can be included as well, for more flexibility). The brush engine does not require to be completely rewritten, only one or two lines of code (for the bit comparison) would be inserted where the tip shape is added to the stroke. Note that this issue/inconvenient was related here, as well: Anyway, I hope this is solved soon.

Yes, it can be understood as a tint replacement depending on the pressure, instead of tint accumulation, but there is an important exception to that: lighter pixels should not replace darker pixels, that's why I referred to "Darker Color" blend mode previously, as a possible bug. All the best.

I already tried it and, furthermore, I tried all the blend modes without success. I think blending is not working properly or the brush engine concept is not correct. Thanks for your attempt to help @Old Bruce

@Lisbon Very much appreciated, thanks!

@Old Bruce Why should I turn off the dynamics. Pencils respond to pressure, they're not felt pens. What I need is a BLEND MODE that works properly, that's the bug I'm referring to.

1. Pencils may have different softness, for instance 4B, HB or 4H, meaning they have a maximum value or opacity, 4B is the darkest but never reaches black. 2. It works with a mouse, not with a graphic tablet since the pen pressure affects the opacity.

Well, from the example, I deduce you are probably using a mouse, not a graphic tablet. Depending on pen pressure, alpha/transparency may vary from minimum 0% to maximum 100% so, we have a problem with opacity, right? I mean, if you repeat your example with a graphic tablet, the second cross will have the same darkening problem. Thanks @Lisbon.

In order to avoid the darkening, I think the most appropiate blending mode should be "darker color" but it doesn't work as I expected because the brush paints lighter color pixels as well. Thank you @Lisbon

Yes, it's a brush with 100% opacity at maximum pen pressure so, under 100% most of the time. Then, it does not have texture, some rotation and flow jitter though. BTW, the darkening occurs with and without texture because the problem seems to be the "Blend Mode", I think.

I want to create a pencil brush for sketching but I discovered that it is not possible in AP because, as you can see in the picture, the strokes accumulate tint at their superimposed parts, where the lines intersect. A properly usable pencil should have a maximum limit of pigment/tint or, at least, a way to allow color replacement only if the stroke is darker, depending on pen pressure. A logical solution could be setting Blend Mode = "Darker Color" but the brush engine doesn't paint strokes over white, I don't understand why. Not even "subtract", "difference" or "exclusion" modes work as expected, using black color brush over white canvas.

Affinity Photo brush editor seems complete although it requires a pair of important blending modes similar to the existing "darker color" but allowing to cover transparent pixels; these new modes could be called, for instance, mix if less transparent (or mix if more opaque) and replace if less transparent (or replace if more opaque) or something shorter. If you don't understand the above explanation or think it is not important then try to repeat the same pencil hatching I did in the uploaded video, and you will come to the conclusion that it is not possible to get such a smooth and easily controllable hatching in Affinity Photo. I hope these 2 options will be added in future releases, they're so convenient and easy to implement. Thanks for paying attention. pencil-hatching.mp4

Hello again! First, let me correct the title which should be something like this: Brush editor downsides (real strokes are different from preview) sorry for my bad English, btw. As you perfectly explained previously, some brush values are editable from outside the brush editor window, and it's ok, but the downside to having a stroke preview that does not coincide with the expected real strokes is that the brush editor UI becomes visually confusing, as you could have noticed in the attached image: 1. Top example: Preview stroke is opaque while real strokes are transparent. 2. Bottom example: Preview stroke is transparent while real strokes are opaque. To be franc, it's a bit confusing for my way of thinking. Finally, thank you for your thoroughful explanations and, please, consider that my erratic use of your software could easily be affecting more users. Anyway, I hope Affinity team will appreciate my feedback as I probably would.
