Tips
Accessing the active brush through the Blender Python API
To get the currently active brush in “Sculpt” mode with the Blender Python API we can use the following command:
|
1 2 3 |
bpy.context.tool_settings.sculpt.brush # bpy.data.brushes['SculptDraw'] |
Snapping a mesh to the desired armature bone
To manipulate an object with an armature, if we only need to ensure that a bone has a full influence on it, we can snap the object not to the whole armature, but directly to the desired bone.
How to find which collection contains the desired object
If the object you need is located in a hidden collection, it can be difficult to find it in large scenes.
To find out in which collection the desired object is located by its type, we need to execute the following. For example for cameras:
|
1 2 3 |
[(obj.name, obj.users_collection) for obj in bpy.data.objects if obj.type=='CAMERA'] # [('Camera', (bpy.data.collections['camera'],))] |
This code will return a list of cameras and collections in which they are located.
Applying mesh modifiers from keyboard
Modifiers can be applied to a mesh from the keyboard. To apply the modifier, move the mouse cursor over it and press the key combination:
ctrl + a
How to get the number of triangles in a mesh
To get the number of vertices, edges, and polygons in a mesh, we can simply take their amount from the desired data block: “vertices”, “edges”, and “polygons”. However, there is no special data block for triangles in the mesh structure.
To get the number of triangles in the mesh, we need to execute the following code:
Deselect all with a single pressing of the “a” keycode
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.
- Open the “Preferences” window
- Switch to the “KeyMap” section
- Turn on the “Select All Toggles” checkbox in the “Preferences” subsection
- Save the settings by pressing the “Save Preferences” button in the upper right corner of the window.
Now the selection of all objects/geometry and their total deselection will be performed by pressing the single “a” key.
Quickly registering Blender to open blend-files by double-clicking
To register Blender to open *.blend files by double-clicking we need to:
- Open the Windows Explorer (My Computer) and switch to the Blender directory.

How to scroll animation in the Viewport window
To scroll the animation in Blender without leaving the “Viewport” window – hold the Alt key and turn the mouse wheel.
This type of animation scroll works even if there is no “TimeLine” window open.
Remove doubles in Blender 2.83
In the last Blender 2.83 version, the function to remove doubles and merge vertices is moved to the “m” key code. The “alt + m” key code, used before, now executes the “Split” functions.
