SUMMARY Standard filter blur brush doesn't respond to Pressure/opacity slider . No matter how hard you draw brush work the same ( blur image on the same level ) STEPS TO REPRODUCE 1. Use standard brush " filter_blur" 2. 3. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Any news ?
Sorry, no. We haven't even had time to try to reproduce the issue yet. The opacity option probably should be disabled because it doesn't make much sense for this brush engine.
Why no senase ? its only way for gradation of filter effect , from little to max blur ;)
Because this is a filter brush, not a generic blending brush. It applies a filter, and filters aren't aware of things like pressure sensors. There would have to be a generic way to connect input sensors to filter parameters, and that does not exist at this point.
Using the latest 4.3.0 pre-alpha appimage, with 166 Filter Blur Motion, 23.3 Filter Blur and 60 x) Filter Blur, I find that the brushes do respond to Toolbar Opacity slider variation but do not respond to stylus pressure variation.
Then I'll confirm for Ahab's observation.
Here there is a bug that the filter brush won't react to the Opacity curve (no matter, pressure, or distance or something else), which is probably easily fixable (?), and a wish to make filter brush engine filter options react to sensors (which is a much bigger task).
Re-confirmed for 5.2.6. Fingers crossed it was an easy fix all along (making filter brushes respond to pen pressure for opacity).
