Blender

get, set, update

“set” – is something like, you pour whiskey into a glass,
and “update” is like – “Wow, whiskey has appeared in the glass, it needs to drink!”,
and “get” – if your friend asks – “What’s in the glass?”, and you answer – “Whiskey”. Or – “Tea”.

How to apply modifier on selected objects

To apply an object modifier with the Blender Python API we can use the “bpy.ops.object.modifier_apply” operator. However, it processes only the active object.

If we need to apply a modifier, for example – Subdivision Surface, to several selected objects, we need to make each of them active, and then call the “modifier_apply” operator.
