Short description of error
Here the blenderartists thread with some history since last year.
But basically, I'm having problems with pen pressure using Wacom intuos 4, 5, bamboo and Cintiq 12wx (I also remember I had the same problem with a cintiq companion 13 inches).
Not sure how is this happening but, there are days that pen pressure kinda works, but I don't remember since when I don't have pen pressure, probably about 3 months.

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

  • Open blender > cube(multi res modifier)> apply> pressure not working...
  • Open blender > cube (ctrl+D) for dynatopo > pressure not working...

I have all the settings the right way to use and is not working, I can tell because every other software pen pressure is working correctly (photoshop, krita, gimp, zbrush, substance painter, 3dcoat).

I also have my wacom driver up to date as well the nvidia driver.

Thanks for the help in advance.

We need some windows dev with wacom tablet to investigate this… :/

I can not reproduce the issue with Intuos 5 on a fresh Windows 10 machine. All i did was installing latets driver from Wacom website.

So please test whether completely re-installing driver (removing it first, then installign the latest one from wacom) solves the issue.

If that doesn't help, check if you can reproduce the issue with same tablet on another machine.

You can also test with File > Load Factory Settings to see if any non-default Blender setting or addon is causing problems, and check if you changed any settings in the Wacom drivers that might have an effect on Blender.

Problem solved, don't trust Wacom when it says to update your drivers even if it ask to uninstall. Do this every time you get an update for your Wacom even if you have multiple Wacom devices: Uninstall manually > download latest drivers from their official web page > install > restart. After that, Blender has pen pressure again. Now I'm happy :D
