Welcome to TVPaint Community forums !

Hi
I'm using TVPaint 10.5.7 on Surface Pro 4( windows 10) and the pressure sensitivity is not working. It works well in Photoshop though.
Is there any way to fix it? Thank you!

hello, it works here.

what is the tool you are using ?
We need a screenshot of its parameters. Are they linked to "Pressure" ?

Otherwise, you can also try to go into the preferences and try to (un)check "Wintab".
