Mask AI v1.3.6

November 19, 2020

Windows: full | online

Mac: full | online

Major features

  • Configurable toolbar positions (in preferences)
  • New look to the application, more consistent with other apps
  • Improved tutorial indicators


  • Save dialog defaults to maximum quality for JPG and PNG
  • Save setting for color profile is now “sticky” between saves
  • more zoom shortcuts
  • Masking brush easier to see while drawing
  • better anti-aliasing on in-app images and icons


  • User auth stuck in “Unable to Verify Ownership” when an incorrect password is entered.
  • mis-matched color depth for background colors, caused discrepancy between selection and preview image
  • File saving folder path persists across multiple saves

let us know how folks like the new UI!

Hi Brad, Like the UI but just noticed that Mask AI was still running in a background process long after I exited.

I created a DMP file for you before shutting down the process so let me know if you want it.

I used the Windows full installer on Win10 PC.

Program starts then crashes as splash screen appears. I tried rebooting to no avail.

Thanks @AiDon. We did switch the framework used in Mask as part of this update, but it should just match what we use in Gigapixel and DeNoise now.

Are you only seeing this in Mask?


Oh no, sorry to hear that that’s what is happening. We had done our own testing and it has been working.

What version of Windows 10 are you using?

how find Windows 10 version

Version 2004 OS Build 19041.630

Yes Brad, only in Mask at the moment. It may be associated with clicking the X on the top right to exit whilst calculating a mask as it exists immediately.

bug report:

The displayed brush size corresponds to the black point (i don’t know why this was not taken from the screengrab), the blue mask to what is drawn.

Usually I use mask only when every other solution of photoshop fails.
Here i wanted to select the sky to adjust its color.

Win 10 PC

Installation took a little longer than normal for some reason. Ran the program with no difficulties whatsoever.
Used the following preferences:

Can you upload your logs?

SInce it crashes immediately I have not been able to turn logging on. There are no logs in the normal location.

The new program keeps crashing when using from Photoshop. I get "Error: plug-in has crashed.
I’ve uninstalled and re installed and nothing is working.

Here’s how to turn file logging on outside of the application:

  1. Go to the search menu in Windows (hit the Windows key on your keyboard, start typing, or hit the spyglass icon on your taskbar)
  2. Type in reg
  3. Click Registry Editor
  4. In the search bar at the top, paste in Computer\HKEY_CURRENT_USER\SOFTWARE\Topaz Labs LLC\Topaz Mask AI\appMain
  5. This’ll open up a folder, you’ll need to double-click fileLoggingEnabled, type in true, then hit enter

Here’s a screenshot to help:

Now if you try to start the program, does a log file get generated?

Here is my log file

Also have brush size issue mentioned above. Actual brush stroke much larger than indicated brush circle. Makes it tough to outline subjects. At least I know I’m not alone!

Hello Taylor,

Untypical problem
Your program Topaz Mask AI 1.3.6 doesn’t even start:

Win says: “The application was unable to start correctly (0xc0000005)”

System: Win 7 pro, 64-bit, service packed.

  • Installed from full, commercial installer (production version)
  • Mask AI (any version) never installed before
  • Your other programs still work great (incl. Studio 1/2, Simplify, and some betas before the end of trial), also all software from my laptop.


Hi There,

I recently bought Mask AI, and i was wondering if the fact that the pixel paint (keep , discard, compute) overlaps or is bigger then the selected cursor size. this is obviously really problematic as it require numerous repaints in detailed parts of a picture.

is this a known topic?
