In most cases, UV elements (vertices, edges, faces, islands) can be freely moved anywhere in the UV Edit area. However, sometimes it is undesirable to move the UV beyond the boundaries of the base UV borders, for example, to ensure that the UV does not “move away” when baking it into atlases.

When defining custom operators in Blender, we can make them cancellable and uncancellable by specifying the “UNDO” value in the “bl_options” parameter of the operator. But what if we need to exclude an existing operator, for example, a system operator, from the undo queue? This is very easy to do by redefining the operator with our own, without specifying “UNDO” in its parameters.

Defining operators, we most often provide for the ability to undo the action they performed – if after executing the operator the user presses the Ctrl + z key combination, all the effects of the operator on the scene should be canceled. However, in some cases, it may be necessary to define an operator that will be ignored if the user tries to undo its actions. Blender’s API allows us to create both types of operators by simply specifying the ability or prohibition of undo in their parameters.
We can use custom icons, icons loaded from external files, and not embedded in Blender libraries, for example, to add customization to operator call buttons in UI panels. However, it is not only buttons that may require custom icons. Using the Blender Python API, we can add customization to drop-down list items or switches that are created based on the EnumProperty type.
The icons used in the Blender user interface, as well as in add-ons, are embedded in the program libraries and are not stored separately. If you need these icons separately for something, you can get them from the Blender developers website.
In Blender 4.1 and earlier versions, the diffuse glow effect for the EEVEE render engine was simply enabled by checking the special “Bloom” checkbox in the Properties panel on the Render Properties tab. In Blender 4.2, due to the upgrading to the new version of the EEVEE-Next render engine, this tab was removed, and now we can’t enable or disable the bloom effect with one button.
In Blender version 4.1 and below, all add-ons were installed locally. To install the add-on, we have to download it to our computer, open the Preferences area, switch to the Add-ons tab and install the add-on by clicking on the Install button. Starting with version 4.2, extensions opened – add-ons published online became available for installation.
In order to display the value of a socket on the Geometry Nodes modifier panel in Blender, we simply need to create a link and connect the desired socket of the desired node with an empty socket on the Group Input node. After this, a field appears in the modifier panel in which we can change the value of the desired socket. We can then place this field on the user panel by accessing it as a dynamic property.
