Affinity comes complete with a range of preset vector brushes which you can customise to suit your needs. Alternatively, you can create a custom brush from scratch using your own image.
To modify a preset vector brush:
On the Brushes Studio, long press a chosen brush and tap Edit. To create a copy of the brush to modify instead of editing the original, long press a chosen brush and tap Duplicate, then locate your duplicated brush at the bottom of the same brush category and Edit that brush instead.
Adjust the settings in the Properties or Controller section.
To create a new vector brush on the fly:
On the Brushes Studio, select a brush.
Adjust the settings as you paint on the context toolbar, accessing additional settings via the More button.
Tap Save from the More section to save your edited brush as a new brush which can be found at the bottom of the same category as the brush you initially selected.
To create a custom preset brush stroke from scratch:
On the Brushes Studio, tap Studio preferences and then select:
New Solid Brush—creates a basic, solid vector stroke via a Brush Editor dialog.
New Textured Intensity Brush—creates a brush stroke based on the opacity values of a raster image. In the pop-up dialog, navigate to and select a file, then edit the Brush Editor dialog.
New Textured Image Brush—creates a brush stroke based on the colour values of a raster image. In the pop-up dialog, navigate to and select a file, then edit the Brush Editor dialog.
The new brush is added to the selected category using default settings.
