We can export any mesh from Blender to a file in OBJ format by selecting it and pressing the following items from the main menu: FIle – Export – Wavefront (.obj). If we need to split the scene into objects and export each of them to OBJ, this process can be easily automated.
In order to quickly “recalculate the normals” – change the direction of the normals so that they are all directed towards the outer surface of the mesh, using the Blender Python API, we can create a script consisting of just a few lines of code.

One of the popular methods for speeding up rendering 3D scenes is to use LOD – Level Of Details. When using LOD, objects close to the camera have the highest detail, midgrounds have medium detail, and backgrounds objects are very rough and undetailed because they are still almost invisible. Such a scene is rendered much faster than a scene in which all objects have maximum detail.
If we need to quickly rename the desired UV Layer for all selected objects in Blender, we can use a simple Python API script to do this in a one button press.

If a particle system uses a collection with different meshes as its source, we can use the Blender Python API to determine which object is the source of each particle.
Just like the common mesh data structure, the “bmesh” object contains the concept of the currently “active” vertex. We can find out which vertex is considered as active in the bmesh, and also assign the active vertex in the bmesh using the Blender Python API.
In general, gizmos looks like arrows and circles on a 3D object with which we can move, rotate and scale the mesh. However, in Blender, the gizmo object is more versatile and can be used to suit our needs in different workspaces. For example, we can create a gizmo to adjust the start and end points of the timeline.
We can enable or disable a collection that contains a specific object using the Blender Python API with a simple script. For example, let’s turn off the collection in which the currently selected object is.
We can quickly activate all collections in Blender on the current view layer – enable the “checkbox”, “eye” and “monitor” icons for all of them, using a simple script.
For different work directions in Blender, separate startup configurations are organized – sets of basic settings for scene parameters, rendering and user interface. Each configuration is stored in a separate file and is loaded from it when the user opens Blender or executes the “File – New” command from the main menu.
