Blender crash on Action that scales and moves UV islands

[baroquedub]

Blender crashes when trying to run an action that attempts to scale and move selected UV islands.

The action was recorded using keyboard shortcuts (e.g. S 0.75 [enter] G X -0.12 [enter] G Y 0.225 [enter])

To Reproduce Enter UV edit mode Select UVs Create Action Go into record Type S 0.5 [enter] G X 0.25 [enter] G Y -0.5 [enter] Stop record Reset UVs to previous (just for debugging purposes) Press 'Play' on Action

Expected behavior In the UV editor, with some UV islands selected, they should be scaled and moved in the same way as the recorded Action Instead, Blender crashes

• Add-on Version 4.07
• Blender Version 3.4.1
• OS: Windows10

Here is a temporary solution: you can add your commands to a script and run this script as an action

Instructions:

import bpy
# Your recording / macros
bpy.ops.transform.resize(value=(0.5, 0.5, 0.5), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=False, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False, snap=False, snap_elements={'INCREMENT'}, use_snap_project=False, snap_target='CLOSEST', use_snap_self=True, use_snap_edit=True, use_snap_nonedit=True, use_snap_selectable=False)
bpy.ops.transform.translate(value=(0.25, -0.25, 0), orient_axis_ortho='X', orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', mirror=False, use_proportional_edit=False, proportional_edit_falloff='SMOOTH', proportional_size=1, use_proportional_connected=False, use_proportional_projected=False, snap=False, snap_elements={'INCREMENT'}, use_snap_project=False, snap_target='CLOSEST', use_snap_self=True, use_snap_edit=True, use_snap_nonedit=True, use_snap_selectable=False)

Copy this and paste it into a Text in the TextEditor (the name of the Text does not matter) now you can add this text as a script event in ActionRecorder

This bug might be an issue of Blender. I will open a bug report in Blender and will add a workaround in the next Version (4.0.8).

I noticed another problem, the action was not recorded correctly. This bug is already fixed and will be in the next Version (4.0.8).

Can confirm that temporary solution of using script events works well. Thank you!

ok, this fixed in Version 4.0.8
