Mouse velocity does not work

[jsampson45]

In Designer v2.3.1 on Windows 10, using Evoluent Mouse Manager v. 6.0.9.3, mouse velocity has no effect when using the Vector Brush tool. Does velocity work with all mouse drivers or hardware, or are there some which negate it?

Should probably be mouse driver & brush controller setting related, thus you have to try out. - See therefor ...

  Whether you're using vector-based Pen, Pencil or brush tools, or pixel-based brush or retouch tools, you can simply connect your device and you're ready to go.

  For mouse users, Affinity Designer lets your mouse become velocity sensitive by default. The same brush tools can be used but with simulated pressure sensitivity based on the speed (velocity) of your mouse movements.

  This automatic response is governed by the brush controller which is set to automatic by default—it senses the type of input device and varies brush size, flow, etc. as you paint according to a particular input: 'Pressure', 'Velocity', 'Brush Defaults', or 'None'. If set to 'None', the brush is always a fixed size, flow setting, etc. Otherwise, the brush stroke properties will vary from a minimum to maximum amount (e.g. the full brush width).

Yes, I have tried it out. It does not work. Which mouse-type input devices are known to transmit velocity to Affinity Designer, if Evoluent mice do not?

I'm not aware of any requirement for any third party mouse management software in order for the velocity controller to work within the app, the size of the stroke dynamically changes dependant on the speed of the mouse movement/stroke on the canvas. I don't have an Evoluent mouse so I can't test their manager app but on my Windows Laptop i'm using a Basic Microsoft optical mouse with no third party software and Velocity works as expected.

I'd suggest opening the brush editor on your active brush (Under 'More' on the context toolbar) and setting the size variance to 100%, use a default pressure profile, set the controller to Velocity and then try alternating between slower and faster strokes on the canvas to 100% confirm if it is responding correctly.

Thanks, I have done this but changing speed of movement of mouse has no effect on the stroke, either width or density. If I needed to demonstrate this I would need to find how to make a video of it.

I am posting a video here (if I can). I am new to videos but in showing what I am doing it may become evident what I am doing wrong.

When I use a mouse (mac, V1) not only the mouse dragging speed matters but also a minimal lengths of a drawn line is fundamentally. A large stroke width gets achieved only over a long distance and with a very high dragging speed (a speed which doesn't allow to draw a certain shape).

With same brush settings and "pressure" instead of "velocity" a Wacom Pen creates much more variance and at a reasonable low, usual drawing speed that also allows handwriting.

Also when drawing with mouse the brush option > pressure curve matters a lot. Other than expected I get the most change in line width with the straight 45º setting, while both a concave or convex curve result in less variance.

 

Thus, when drawing with the mouse, I prefer to set/edit the curve after drawing manually via "Stroke" > "Pressure". For more complex illustrations the mouse isn't by far a substitute for a pen, not because of the different handling/moving but because the extremely low effect of the pressure/velocity curve.
