Aligning the origin to the bottom for all selected objects using the Blender Python API

Nikita

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.

Removing custom normals from all selected objects in Blender

Nikita

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.

Removing a modifier from all selected objects using Blender Python API

Nikita

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.
