Switching the selection mode between vertices, edges, and polygons in mesh edit mode is mapped by default to pressing the 1, 2, and 3 keycodes on the keyboard. However, if it is more comfortable to use these hotkeys for other functions, we can change this mapping.

Since Blender 2.80 the deselect all function – complete deselection of all objects or geometry – has been switched from a single press of the “a” key to a double “a-a” or a combination of “alt+a” keycodes. To return the deselection function to a single “a” press, we can edit the settings of the selection operators. Or, since Blender 2.81, a special checkbox is provided for this in the keyboard shortcuts settings.
Now the selection of all objects/geometry and their total deselection will be performed by pressing the single “a” key.
To switch to the view from the active camera we can execute the following command:
|
1 |
bpy.ops.view3d.view_camera() |
This operator works in the toggle mode, so the next executing of the same command returns the view to the previous state.

To switch from a global coordinate system to a local coordinate system of an object, we need to multiply the global coordinates by the inverted matrix of an object:
|
1 2 3 4 5 |
import copy object_matrix_inverted = copy.copy(bpy.context.object.matrix_world) object_matrix_inverted.invert() cursor_location_local = object_matrix_inverted @ bpy.context.scene.cursor.location |
To switch from the local coordinate system of the object to the global coordinate system, we need to multiply the local coordinates by the matrix of an object:
|
1 2 3 4 5 |
import copy object_matrix = copy.copy(bpy.context.object.matrix_world) vertex_0 = bpy.context.object.data.vertices[0].co vertex_0_global = object_matrix @ vertex_0 |
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:
Knife Project is a powerful Blender tool for quickly cutting holes of various shapes in objects.
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?
To make glass objects render faster and cleaner in Cycles render engine, we can adjust glass material processing by the number of beam bounces.
