To enable color highlighting of mesh polygon orientation, we need to on the “Face Orientation” checkbox in the “Viewport Overlays” menu. To turn off the highlighting, we need to uncheck this checkbox. This can be done either manually or using the Blender Python API.

Since Blender 4.4, the color scheme for displaying polygon orientation in the 3D viewport has changed. When in previous versions polygons that had the front orientation (normals are directed “outward” of the mesh) were displayed in blue, then in version 4.4 these polygons are not highlighted at all.

Render passes are additional images that are created during rendering and that carry some separate additional information about the render. For example, this could be a depth map – a black and white image in which the brightness of the white color corresponds to the distance of objects from the camera. The creation of such render passes can be turned on in Blender by the user manually in the Properties area on the View Layer tab or using the Blender Python API.

When using typing in code that calls the Blender Python API, we usually don’t encounter any problems. However, specifying the return type for the execute() function of the Blender operator is not entirely obvious.

The geometry of objects in Blender is always built around the origin – a point that is taken as the starting point in the object’s local coordinate system. And if the origin does not lie in the plane of the object’s base, it can be difficult to place this object on the surface of another object. We can quickly set the origin to the bottom for all selected objects in the scene, writing a script using the Blender Python API.

Animation keys can be set on scene objects either manually (by pressing the “i” key) or using the Blender Python API, for this purpose the developers have provided the keyframe_insert() function.

Most often, we need to clear custom normals when importing objects from external scenes. We can remove custom normals manually by selecting meshes in the scene and pressing the Clear Custom Split Normals Data button in the Properties panel on the Data tab of the object. However, if there are many such objects, we can write a simple script using Blender Python API that will quickly clear the normals on all selected objects.

When developing add-ons for Blender, we may need to programmatically switch 3D viewport modes – for example, enable the WIREFRAME grid display mode.

Assigning and removing modifiers in Blender is done separately for each object. However, if we need to, for example, remove a modifier from many objects in a complex scene, removing them from each object individually will be long and inefficient. Using the Blender Python API, we can write a simple script that will remove modifiers from all selected objects in the scene.

Unfortunately, the developers have not yet provided access to the Quick Favorites menu via the Python API in Blender. However, it is possible to transfer the entire menu to the user panel. We can simply draw the Quick Favorites content on the user panel layout.
