We can delete collections in Blender through the “collections” list in “bpy.data”.
To remove a collection we need to use the “remove” method from the collections list, specifying the collection to be removed in the parameter:

We can assign constraints to objects through the object “constraints” property.
To add a constraint to the currently active object, we need to create a new constraint in the object’s “constraints” list, specifying its type in the parameters:

To improve the speed and convenience of developing Blender add-ons with Microsoft Visual Studio Code, this IDE can show the code auto-completion for common Blender API types.
This way of adding autocomplete is by Zen3515.
Blender Python API autocomplete modules: fake-bpy-modules by Nutti update – added branch for Blender 2.91.
Last release: 2020.12.16.

The camera angle in Blender can be set both in millimeters – the Focal Length parameter, and in degrees – the Field of View parameter.
To get the Field of View in degrees from the Focal Length value in millimeters, we can use the following formula:

We can access vertex groups for the active mesh through its “vertex_groups” structure.

To make a new UV with the Python API and set coordinates to its points, we need:
First – create a new UV with the desired name:
|
1 |
new_uv = bpy.context.active_object.data.uv_layers.new(name='NewUV') |
Next, to specify the coordinates of its points, we need to cycle through all the “loops” of the mesh:

You may need to get a list of coordinates of the mesh’s UV, for example, when exporting a mesh from Blender’s internal format to any external formats.
A list of the mesh UV-s can be got by accessing the “uv_layers” structure:
|
1 2 3 |
bpy.context.object.data.uv_layers[:] # [bpy.data.meshes['Cube'].uv_layers["UVMap"], bpy.data.meshes['Cube'].uv_layers["UVMap.001"]] |
To completely remove the object from the scene through the Blender Python API do the following:
Open the “Text Editor” window.

We can get a list of all available shader nodes by their type.
To start, add any object to the scene, for example, a cube, create material for it, and delete all nodes. Here, in this material, we will display all the shader nodes available in Blender.
