Delete Geometry Node
Geometry Nodes has a node that allows us to remove required vertices from a mesh. This is the “Delete Geometry” node.

Difference between the “eye” and the “monitor” icons when hiding objects
To hide objects in the 3D Viewport window, we can click the “eye” icon in the outliner near the desired object name (press the “H” shortcode), or we can click the icon with the “monitor” image. In both cases, the object will be hidden.
So, what’s the difference between these two variants?
It is very simple:
Clicking on the “eye” icon hides objects only in the currently active scene of the blend file.
Pressing the icon with the “monitor” hides objects in all scenes of the blend file at once.
Using UV coordinates for working with mesh geometry
With the coordinates of the UV, we can manipulate not only materials but also the geometry of the mesh itself. We can connect the UV coordinates with the mesh geometry using “Geometry Nodes” in Blender.

Mixing materials by the UV coordinates
UV coordinates can be used for mixing materials directly on the mesh. This can be useful if, for example, the shape of the mesh is cylindrical or closed or the UV boundaries correspond to the boundaries of the mesh.
How to apply transformations to a mesh with the Blender Python API
To apply all transformations to an object, all its vertices must be multiplied by its global matrix, the matrix itself must be made identity.
To apply all transformations to the active mesh, we need to execute the following:
|
1 2 3 4 5 6 7 |
import bpy obj = bpy.context.object matrix = obj.matrix_world.copy() for vert in obj.data.vertices: vert.co = matrix @ vert.co obj.matrix_world.identity() |
Message Bus
In Blender API there is a module that we can use to track the changes of any object’s properties available through the Python API. This module names “Message Bus”.
Let’s look at how we can make an event handler function to track changes to a property. For example – the location of the 3D cursor.
