How to make node connections in Blender 2.8 not straight, but curving as before

In Blender 2.8 node connectors in the “Shader Editor” window are straight by default, unlike earlier versions, where they bent curving. To return the usual connections bend, change the following settings:

  • Open the “Preferences” window
  • Switch to “Themes”
  • Expand the “Node Editor” tree branch
  • In the “Node Curving” field, set the value greater than 0. 0 means straight lines, the larger – the greater bend. A value of 4 corresponds to the bend that was in Blender 2.7x versions.

  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

  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

Where did the code completion in the python console in Blender 2.82 disappear

In Blender 2.81 and earlier, you could see the possible code completion by pressing “ctrl + space” in the python console. This key-shot shows nothing in Blender 2.82.

Code autocompletion in the python console was not removed in 2.82, it was moved to the “tab” key.

User interface elements alignment by columns

Interface elements in custom user panels often do not correspond to each other in size. As a result – the overall panel layout does not look beautiful. As an example, let’s create a custom panel and place an operator button and an input text field on it.

Can we make it more accurate?

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.

Vertex selection fine tuning in Blender 2.8x

In Blender 2.79, mesh vertices were highlighted in the “tweak” selection mode by holding down the “shift” key and a slight cursor movement with the right mouse button pressed. This allows quickly add vertexes to the selection without aiming each vertex with sniper accuracy.

In Blender 2.8x, this method has become unavailable due to the left click selection change. For those users who remained on “the right click select”, nothing has changed, everything works as before. The “tweak” selection was broken only for those who switched to the left click selection.

To use the “tweak” selection with the left click select, you need to make the following changes into the keyboard shortcut settings:

How to split and join Blender interface windows thruough the python API

A set of operators is provided in Blender for manipulating with the location of its interface windows.

To split the current window (using the current context) into two in a specified ratio, we need to execute the following operator:

With:

  • direction – set the splitting direction (‘HORIZONTAL’ or ‘VERTICAL’)
