Undo bug in Sculpt mode #71985

Closed
opened 2019-11-27 22:15:04 +01:00 by Ethical Vegan · 7 comments

Steps to reproduce the bug:

  • Go in Sculpt mode
  • Select the Draw brush, and set the Radius to 60px (this can be any number)
  • Save the project
  • Open the project (you are now directly in the Sculpt mode)
  • Change the brush Radius to 200px (this can be any number)
  • Make a single stroke on the mesh
  • Undo this stroke -> BUG: the undo will take more time then usual, it will reset the Radius back to to 60px, and you will not be able to redo the stroke

Note: it is not just the Radius that is reset, but every other brush setting that you changed after opening the project

Note: if you did multiple strokes instead of a single stroke, let's say 2 strokes, then this will happen:

  • first undo: works fine (it did undo the second stroke)
  • second undo -> BUG
  • first redo -> nothing
  • second redo -> the 2 strokes appear at once (but the Radius is still reset back to 60px)

I would think this can be confirmed.

I know there have been a couple of changed to sculptmode undo, but this still seems wrong when changing brush radius.

@PabloDobarro , @ideasman42 : is this the way it is supposed to work?

For sure it is not the way it is supposed to work. The workaround for this bug is to simply go out and back in the Sculpt mode every time you open a project that starts in Sculpt mode.
