Grease Pencil sculpt mode is not working. It doesn't even show the circle that we use for sculpting. I've been testing 2.83 Alpha version for the last two weeks and sculpt mode never worked.

Exact steps for others to reproduce the error

Launch Blender
New 2D Animation file
Select Draw mode
Draw
Select Sculpt Mode = No function.

Thanks!

I cannot replicate.

Can you try to reset the Sculpt brushes? Do you have the problem with new files, old files?

Goes away here with Factory Settings, or when resetting Sculpt Brushes...

@antoniov : are you aware when this started? should there be versioning code?

@lichtwerk In theory the patching is done... I'm going to recheck. The error you have is the missing Brush.

I cannot reproduce with the source code of today starting with --factory-startup or using the menu option Factory Settings

What I did was:

Open default template or start blender with --factory-startup
Add GPencil object Stroke or Blank Stroke and Draw something
Go to Sculpt

Hi,

With new files, if I reset brushes, circle appears and I can sculpt.
If I save the file, the issue is resolved for the file but same issue occurs with any new file.
I tested old files. Only one of them shows the circle without needing to reset.
After resetting the brushes for an old file, if I save it, I can sculplt when I open again. However, when I first open the sculpt mode on a saved file, circle is missing while sculpt functions work. I have to go to draw mode and change it to sculpt mode again for the circle to appear.
If I don't save an old file, issue repeats.

@tbrimbo There are different things here:

If you open an old file, it's logic you need save it to get all functionality. We have done a total refactor of the Sculpt brushes and when you save it all is reseted as it must be.

For the cursor (the circle), I'm not sure because this area is not only GPencil, but a more general cursor handlid.... just check that you have the cursor enabled:

When you say "new file"...how do you create the file? open default template and add a GPencil object or using 2D template?

When I first started Blender I loaded factory settings and saved start up file, issue is now resolved for all new files.
It was happening with both 2D template and when I added new GPencil object.
Cursor is enabled. If I open the file while sculpt mode is enabled, it doesn't show the circle. I have to go to draw mode and back to sculpt mode to see the circle. This is a minor issue. At least I can use the sculpt mode again.
Thank you for your time.

I just downloaded 2.83 and only a handful of the sculpt tools work now. Any idea what I can do?

@Pineapple Did you test with 2D template? and with factory settings?

Hi, I'm having a similar issue. At some point, a GP tool stops working. I'm not sure how that happens, but it happened to me 3 times in just a few hours of using Blender 2.83 (it happens with files created in the same version). Fortunately, resetting the brushes does fix the problem.

It has happened to me with the Push tool and the Strength tool. Here is a file that has the problem with the Strength tool: chat_bug2.blend

There are multiple symptoms when trying to use the tool:

The cursor does not appear
Clicking and dragging in the viewport does nothing
In the tool settings (?), above the viewport, there is only a radius setting available.
In the status bar, instead of saying "Stroke Sculpt" for the LMB, it says "Select"
When clicking on the X-ray button in the top-right of the viewport, a blank error message appears.

You can see all these symptoms in this video:
