Objects pointers brokes if undo/redo operation is used

In Blender 2.8x the undo/redo operation system (ctrl+z / ctrl+shift+z) has been completely rebuilt. One of the results of this API change is when the undo operation is performed, all objects in the scene are fully recreated – the current object is destroyed, and a completely new object is created instead. Pointers to the old objects (before the undo operation) now point to invalid objects that can no longer be used.

Add-ons reload through the F8 key shot

Add-ons are not reloaded by pressing the F8 key in the Preferences – Add-ons window in Blender 2.83. The add-ons reload function call with this key shot was no longer tied starting with Blender 2.80.

To bind the add-ons reloading to the F8 key shot again:

  1. Open the “Preferences” window
  2. Open the the “Keymap” section
  3. Expand the “Screen – Screen (Global)” branch
  4. Press the “Add new” button at the bottom of the list
  5. In the operator identifier field, type “script.reload”
  6. Click on the keyboard field and press F8 to bind this key to the specified operator call
  7. Press the “Save Preferences” button to save new settings

How to open folders by a single click in Blender 2.8x

When opening files through the “File Browser” in Blender 2.8x, directories (folders) are opened with mouse double-click. This change has been made for better compatibility with the standards (directories are opened by double-clicking in most file managers, for example, in the Windows Explorer), but this is not always convenient.

To make the folders opening  by a single click:

Some Blender tuning

A few settings that can make your work in Blender a little bit convenient.

Viewport window

Remove the default cube. Each time you open a new scene, you delete it. Let’s do it once.

Remove the lamp light source. In most scenes, you will adjust the lighting in a completely new way.

Put the camera in a separate collection and hide it from the viewport (click on the “eye” in the outliner window), now the camera does not interfere with the scene.
