  1. This concerns defining new Textured Intensity brushes on iPad and MBP. Both are running latest AD2; iPad is latest published iPadOS, MBP (early 2016) is running Monterey 12.6.8, latest for that hardware. I am building experimental TI brushes. My goal is to make them in widths that double from one nozzle to the next. The nozzle widths I’m using are more accident/experiment than insight. The Issue The issue is that I have a TI nozzle I can turn into a brush on the iPad, but the MBP changes the entered width on the MBP. This is the same PNG Nozzle file on both machines. Same brush settings; iPad accepts brush width of 1424px, MBP makes a brush, but reduces that width to 1024px - silently, no alerts for the bug at the keyboard. Surely the upper limit to Nozzle Width should be the same on both iPad and MBP? Making this Mischief On iPad: I made the nozzles using the attached AD2 document, and exported the Nozzles with Export Persona. After making the brushes using the exported PNG files, I used the X8 and X4 variants in the associated Butterfly Wings. My brushes are somewhat crazy, but AD2 did everything as expected. Moving to MBP: I airdropped the iPad AD2 document and PNG Nozzles to my MBP, and set about making the brushes in AD2 for MBP. That’s when I noticed that AD2 was putting the fattest Nozzle on a diet - no 1424px width for the MBP, just 1024px. The Cargo AD2 source document created on iPad, X4 and X8 nozzles. I will add at least a screenshot from my MBP to this bug report shortly. Note Document is 300DPI, reflecting my photographic background, just makes things simpler for my head. These are wide brushes, but I’m very pleased to report that I’ve not seen any hint of performance issues on either of my machines. I’ve played with both Repeat and Stretch setting, no perceptible difference. Brush strokes inside the Butterfly wings deliberately have very acute angles, causing mitre issues/artifacts, which is why some got split into 3 separate segments each.

  2. Hello, Hope you are doing well and staying safe. This is my first ever vector brush. Hope you like the brush that I have created. Download here
  3. I want to know how Affinity Designer decides what the stroke weight of strokes for shape tools should be when applying a textured intensity brush as the stroke with the Brushes panel/studio. In the default set of textured intensity brushes in the Brushes panel/studio, "Classic Pencil HB" from the "Pencils" category (the one that appears at the top of the list for me) has a default brush width of 128. If I select the Vector Brush Tool and then the Classic Pencil HB in the Brushes panel, the "Width:" value in the Context Toolbar says "128 px". However, when I actually draw a curve with the Vector Brush Tool and select the curve with the Move Tool or the Node Tool, the stroke width for that curve says "64 pt"—exactly half. Why isn't it 128 px, like Classic Pencil HB says in the Brushes panel? Likewise, when I create a shape using one of the shape tools, like the Rectangle Tool, and then apply Classic Pencil HB as the stroke, it's also 64 pt. Is this somehow related to the DPI value in the "Document Setup…" dialog box? If so, what is the relationship—how do the mechanics of this work? There appears to be some relationship between pt, px, and DPI that I don't understand.
  4. Happy 2020! If a little late. I am posting some interesting experiments with Texture Intensity brushes for Affinity Designer: http://i-toons.com/archive/CD_illustration_brushes2020.afbrushes.zip These were exported from the 1.8.1 version. This set has several focuses. 1. A fascination with Dave Coopers ink line where a stroke expands and shrinks (pressure) as it is drawn. https://www.youtube.com/watch?v=Aj3BxL85UUE 2. In the olden days of Creature House Expression 3 a feature that produced wonderful textured edges on fills was a favorite of mine for adding… wonderful textured edges to fills! The “edge” was applied to a fill and mapped along the edge of the fill. E3 used a similar technique as ADs textured intensity brushes… The trick to make the edge texture was to have basically a half brush stroke. One edge flat. The rest feathered or textured out as desired. The flat edge mapped directly to the fills edge. There was a little extra voodoo with pixel color at the strokes edge as well…) AD doesn’t have this edge feature - but something like it can be sort of faked. ADs brushes map to fills in a different way - they sort of center the stroke halfway over the edge of a fill. To get a brush to “join” to the fill - I made a brush that mirrors itself - with a 100% dark center. The brush must also meet at its ends so it wraps horizontally as well. The mirrored version seems to blend nicely with a fill - and can wrap in either direction (reverse curves). Some sample of how this looks are in the attached image. Sadly the stroke and fill don’t share the same “intensity” - if transparency is dropped… But the textured edge done this way can look ok. Brushes that don’t mirror like this extend out from the fill but often show hard fill edges. A future AD feature in the making. 3. I had been experimenting with hatch and dot pattern edges - looking for an illustration style I admired - and straying into a dot like airbrush look… See attached brushpower image. The hazy moon glow and sand dunes. AD has a lot going for it. The textured intensity brushes are the main reason I dig this software. The brush engine has a long way to go as I have mentioned in the past: Affinity Designer Brush UI enhancement: Affinity Designer brush-ui enhancement Identify and switch Brush and Stroke attributes option/tool: Switch brush With a little more power in the brush features - this would be such a stellar tool! Here's to 2020 and maybe making an illustrators wishes come true! ; ) If you happen to use any of these brushes. Post an example. I love to see how the brushes are used! Enjoy! Craig
