How to set-up brush opacity change on pressure level with pen?

[souacz]

As in title. Brush size change depending on pressure level works in pen mode but I can't find a method to let it to change opacity on pressure level change. In Photoshop and Artrage it works without problems but not in AP

Thank you, it works but much worse than in Photoshop. I had to set-up Accumulationn to 100% that it would work at all. The transparency only works with really low pressure and quickly passes to 100% opacity when increasing the pressure of the pen. My pen supports 8192 degrees of pressure and in Photoshop it works very linearly

Dear Affinity,

Can we please just have a "OPACITY" Preset under "Dynamics" with your customary controls as all other settings under Dynamics such as: % Slider / Type (None, Random, "Pressure," ect), for both Photo & Designer.

Also... a Pen: "Force to Opacity" button, as there is now (1.7 update) Brush Pen Size would be great too. Perhaps you might want both settings on also; as this is "again," commonly used and it shouldn't be a headache to figure out.

Opacity & Size are the two most commonly used brush settings! Right now, is the best time to beat Adobe but, the jumping through hoops for having Pen Pressure effect "Opacity" only is annoying! Severely annoying!

To Everyone needing help with Pen Pressure for Opacity (1.7 Update):

Affinity Photo/Designer - Pen Opacity Pressure Settings (As of the 1.7 Update): you do not need to adjust Flow or set Flow to "Pressure," to affect Pen Opacity Pressure.
- All you need to do (via the Context Menu with the Brush selected) is:
 1. select "MORE"
 2. choose "Dynamics"
 3. adjust the "ACCUMULATION" slider to 100% and select "Pressure" from the drop down.
 4. Make sure the "Force Size button" is OFF, via the Context Menu; unless you want your brush pressure to affect both size and opacity at the same time, (which isn't uncommon when used with painting &/or blending). Note: you can also set the size to None via the drop-down menu for size in under More/Dynamics. Note: you may have to do this if you're using custom created brushes, such as some brushes made from Daub.

Affinity Photo/Designer - Advanced Pen Opacity Brush Settings & downloaded/purchased Custom Brushes:
5. Advanced Pen Opacity Pressure: under (Brush/Context Menu/More Button/ Dynamics Tab/ACCUMULATION - Set to 100% & Drop Down to "Pressure)" you can also change the "Curve". The best curve to use is the same one for "size." The Curve button is to the "Right" of the Drop-Down menu in the Brush/More/Dynamics tab. Select a curve and try different curve alignments or create your own. The best one or rather for normal one you would expect (as in Adobe PS) is the curve alignment all the way to the Right (which again, is the same Curve used for Pen Size Pressure).
6. Download/Purchased Brushes and Opacity (very important especially for Designer): a lot of brushes already have multiple settings created from those downloaded, purchased or inherently part of Designer. However, older brushes not made specifically for the 1.7 Affinity update may need some adjusting. Flow and Accumulation are the two biggest sliders you must pay attention to if a brush does not behave correctly as it may have in previous additions of Affinity. Example: Daub | Essentials Brush Pack. Some brushes will need tweaking. I suggest coping the brush from the original and adjusting those there in (and Flow), as needed. That way you can save them and back them up as well!

Hope this helps – Johnny K

PS. Sorry for being so "obvious in my descriptions. I want to be clear with those whom never used Affinity before &/or those coming from Adobe. As I mentioned, Affinity really need to get with the program of adding a "FORCE OPACITY BUTTON" to the context menu as they did for Size and list "OPACITY" in the Brush/Context Menu/More Button/Dynamics with all controls, menus and curve alignments as they do for other brush properties. Kinda ridiculous this hasn't been addressed yet!
