To resolve conflicts between add-ons in Blender, it may be necessary to know if Blender base system operator has been overridden with a custom operator in some third-party add-on.

In the Blender Python API, some operators can only be called in the area they are intended for. If we call such an operator in another area, it will not be executed or Blender will throw an error. To call a context-related operator from an area not intended for it, we need to redefine the context.
To get the mesh vertex weights as they are distributed among its vertex groups with the Blender Python API, we need to correlate the vertex group indices with the group indices of the current vertex.
Blender Geometry Nodes has a number of nodes for working with text strings. There are nodes that allow us to convert numbers into text, and replace substrings in a text string. As an example, let’s implement a “countdown” from ten to zero words.
With Blender Geometry Nodes, we can fill the curve with the required number of objects. We can also make the fill a little more interesting by changing the size of the fill objects randomly.

In some cases, it may be necessary to determine whether a certain object is currently visible in the 3D viewport area in Blender or not. We can determine the visibility of an object in a viewport with the Blender Python API using the location_3d_to_region_2d function of the view3d_utils module.

The Blender Python API does not provide a special handlers for tracking View Layers switching. However, if it needs to perform some action when switching them, we can track their switching using the message bus.
Let’s fill the curve with the required number of objects so that they occupy the entire length of the curve without gaps, adjusting their scale if necessary.

Deforming a mesh with texture maps in Blender Geometry Nodes, we can achieve very interesting results. For example, with the Voronoi texture, it is very easy to add a bit of “organic” to any object.
