I notice it is possible to have the size of the brush controlled by pressure, and the opacity controlled by velocity with a brush in the Pixel Persona in Affinity Designer. However, I cannot seem to do this with the Vector Brush tool. Am I missing something? In the Vector Brush options, it will allow me to change from pressure to velocity but it changes for both opacity and size.
Not a bug per-se, but there's a configuration error in Affinity Designer and Photo's raster brush settings while using "Velocity" to control brush size. I noticed this with previous versions and thought it might be addressed in 1.7, but unfortunately it's not. Using velocity to control the brush size is meant to change the brush size depending on the speed at which you draw. Think gel-pen - the quicker you draw, the thinner the line is, and the slower you draw, the thicker the line is. As it stands, in Affinity, it's more of a slow gradual build up in size regardless of the speed at which you draw - sometimes it doesn't really do anything at all to the size. Procreate's 'Gel Pen' brush is a great example of this, and so is ArtStudio Pro's brushes with velocity enabled. Clip Studio Paint also has it, which I used to demo the feature so that you can better understand what I mean. I've uploaded a quick screen recording of this to YouTube to better show what I mean (below). I've boosted the 'velocity' jitter significantly in CSP just to make it obvious, and I've maxed it out in Designer, but it isn't doing much. The velocity feature is super awesome for getting a digital brush to feel and behave 100% like a real ink pen. Would love to see this realised/fixed in a future update.
Hello there, I've been using the Affinity products for a couple of days now and I'm really amazed by their capabilities. However, there seem to be a few disruptive bugs regarding the brush dynamics, both in Photo and Designer. (Note: I decided to name the bugs for future reference) "Prokaryote bug": When using the velocity control on a paint/pixel brush (Photo and Designer), there always appear big blobs at the beginning of each stroke followed by a much thinner tail, no matter how fast or slow I’m drawing. This bug has been reported here and there almost 2 (!) years ago and, yet, remains unfixed. Also, in the brush dynamics window (almost) every slider is called a “jitter”. The word “jitter” is a bit confusing as it implies that the brush is modified randomly over time while, at the same time, corresponding to how fast, or with how much pressure, etc. you draw. In other words, not completely (!) random. This doesn’t seem to be standard/what’s happening in affinity. In my understanding those “jitters” only adjust the (output) amplitude of the effect produced by the (input) controller and don’t yield actual jitter. If randomness is desired, the only option in Affinity would be to set the property to random and, thus, lose control. You cannot have both (control and randomness). Am I correct? And is this the intended behaviour? If so, the use of another word might be advised. "Diamond bug": When velocity is set for a vector brush or pencil, Designer creates jagged (diamond-shaped) brush strokes. If the stroke is rather straight and drawn with high velocity, the rough edges will stay. If the stroke is longer and curvier the jagged stroke tends to turn into a much smoother stroke as soon as the mouse button is released. Nonetheless, the stroke doesn’t seem to reflect the actual velocity changes applied and sometimes the jagged lines don’t disappear entirely. This behaviour has been demonstrated here as well. (Images 1 and 3 are before releasing the mouse button, 2 and 4 are after) "Umbrella bug": Additionally, the (vector) stroke often ends very abruptly in a big semicircle (umbrella), especially when drawing circles/spirals. All of the above-mentioned bugs appear not only in editing mode but also in the exported files: So, it’s not just a visual bug. They, unfortunately, render the velocity control pretty much useless. They also occur with clone brush, dodge & burn, sponge, erase tool and any other brush descendant. Other bugs: When the screen resolution is set to 1366 x 768 (typical laptop display resolution) or lower, the toolbar gets cut-off in Photo. I am aware of the option to undock the toolbar in the view menu but this is quite cumbersome when you start Photo for the very first time. CRITICAL: Batch processing of photos into the same directory and in the same file format as the original files (e.g. to create a lower quality copy) will result in overwritten (yes, deleted!) original photos without any prior warning. A message and an option to append some text to the exported file names would be strongly required. This, also, has been reported (here).I hope this was somewhat helpful and I'd love to see these issues resolved in the near future.
